This document specifies requirements for protective provisions against the effects of stray currents, which result from the operation of DC electric traction power supply systems. As several decades' experience has not shown evident corrosion effects from AC electric traction power supply systems, this document only deals with stray currents flowing from a DC electric traction power supply system. This document applies to all metallic fixed installations which form part of the traction system, and also to any other metallic components located in any position in the earth, which can carry stray currents resulting from the operation of the railway system. This document applies to all new DC lines and to all major revisions to existing DC lines. The principles can also be applied to existing electrified transportation systems where it is necessary to consider the effects of stray currents. This document does not specify working rules for maintenance but provides design requirements to allow maintenance. The range of application includes: a) railways, b) guided mass transport systems such as: 1) tramways, 2) elevated and underground railways, 3) mountain railways, 4) magnetically levitated systems, which use a contact line system, and 5) trolleybus systems, c) material transportation systems. This document does not apply to a) electric traction power supply systems in underground mines, b) cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly from the contact line system and are not endangered by the electric traction power supply system, c) suspended cable cars, d) funicular railways.

This document specifies requirements for the protective provisions relating to electrical safety in fixed installations, when it is reasonably likely that hazardous voltages or currents will arise for people or equipment, as a result of the mutual interaction of AC and DC electric power supply traction systems. It also applies to all aspects of fixed installations that are necessary to ensure electrical safety during maintenance work within electric power supply traction systems. The mutual interaction can be of any of the following kinds: — parallel running of AC and DC electric traction power supply systems; — crossing of AC and DC electric traction power supply systems; — shared use of tracks, buildings or other structures; — system separation sections between AC and DC electric traction power supply systems. The scope is limited to galvanic, inductive and capacitive coupling of the fundamental frequency voltages and currents and their superposition. This document applies to all new lines, extensions and to all major revisions to existing lines for the following electric traction power supply systems: a) railways; b) guided mass transport systems such as: 1) tramways, 2) elevated and underground railways, 3) mountain railways, 4) magnetically levitated systems, which use a contact line system, 5) trolleybus systems, and 6) electric traction power supply systems for road vehicles, which use an overhead contact line system; c) material transportation systems. The document does not apply to: a) electric traction power supply systems in underground mines; b) cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly or via transformers from the contact line system and are not endangered by the electric traction power supply system for railways; c) suspended cable cars; d) funicular railways; e) procedures or rules for maintenance. The rules given in this document can also be applied to mutual interaction with non-electrified tracks, if hazardous voltages or currents can arise from AC or DC electric traction power supply systems.

This document applies to devices for power frequency overvoltage protection (hereafter referred to as "POP") for household and similar uses, with a rated frequency of 50 Hz, 60 Hz or 50/60 Hz, with rated voltage not exceeding 230 V AC (between phase and neutral), and with rated current not exceeding 63 A, either consisting of a functional unit in combination with a main protective device (MPD), or as one single device having opening means able to open the protected circuit in specified conditions. The main protective device is a circuit-breaker, an RCCB or an RCBO. NOTE 1 A POP, as one single device, is not a protective device to be used for automatic disconnection of the supply within the meaning specified in IEC 60364-4-41. POPs are intended for use in an environment with pollution degree 2 and overvoltage category III. Devices for POPs are suitable for isolation. POPs can be designed as a POP unit assembled to or integrated in a main protective device by the manufacturer or as an assembly of a main protective device mechanically or electrically coupled on site with the POP unit, or as one single POP having opening means able to open the protected circuit in specified conditions. POPs are intended to mitigate the effects of power frequency overvoltages between a phase and neutral conductor (e.g. caused by loss of a neutral conductor in the three-phase supply upstream of the POP) for downstream equipment by opening the protected circuit when an overvoltage between phase and neutral is detected. NOTE 2 In this context, the verb "mitigate" means that the POP will provide protection in most cases of power frequency overvoltages. POPs intended for monitoring one line-to-neutral conductor voltage can be used between two-phase conductors in a phase-to-phase electrical supply system not exceeding 230 V if both conductors are switched and declared as such by the manufacturer. POPs according to this document are suitable for use in an IT system provided all active conductors are switched. This document does not apply to protection against common mode overvoltages. This document does not apply to surge protective devices.

This document applies to residual current monitors for household and similar purposes,
having rated operational voltages and a rated voltage of the monitored circuit not exceeding
440 V AC and rated currents not exceeding 125 A.
NOTE 1 The standard for residual current monitors having rated operational voltages and a rated voltage of the
monitored circuit exceeding 440 V AC is in preparation, as IEC 62020-2.
RCMs are intended to monitor the residual current of the installation and to give a warning if
the residual current between a live part and an exposed conductive part or earth exceeds a
predetermined level.
RCMs covered by this document are not intended to be used as protective devices.
RCMs detect residual currents circulating in an AC circuit (e.g. residual alternating current,
residual pulsating direct current, residual smooth direct current), whether suddenly applied or
slowly rising.
NOTE 2 RCMs for DC systems are under consideration.
This document applies to monitors performing simultaneously the functions of detection of the
residual current, of comparison of the value of this current with the residual operating current
of the device and providing the specified warning signal(s) when the residual current exceeds
this value.
RCMs supplied by internal batteries are not covered by this document.
The requirements of this document apply for standard conditions (see 7.1). Additional
requirements can be necessary for RCMs used in locations having severe environmental
conditions.
RCMs are intended for use in an environment with pollution degree 2 and overvoltage
category III. For an environment with a higher pollution degree, enclosures giving the
appropriate degree of protection are used.
RCMs in compliance with this document are suitable for use in TN, TT, and IT systems.
This document does not cover Insulation Monitoring Devices (IMDs), which are covered by the
scope of IEC 61557-8.
NOTE 3 An RCM is distinguished from an IMD in that it is passive in its monitoring function and only responds to
an unbalanced fault current in the installation being monitored. An IMD is active in its monitoring and measuring
functions in that it can measure the balanced and unbalanced insulation resistance or impedance in the installation
(see IEC 61557-8).

IEC 60127-8:2018(E) relates to fuse resistors with particular overcurrent protection rated up to AC 500 V and/or DC 500 V for printed circuits and other substrate systems, used for the protection of electric appliances, electronic equipment and component parts thereof, normally intended to be used indoors. It does not apply to fuse resistors with particular overcurrent protection for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere. The object of this part of IEC 60127 is a) to establish uniform requirements for fuse resistors with particular overcurrent protection so as to protect appliances or parts of appliances in the most suitable way; b) to define the performance of the fuse resistors with particular overcurrent protection, so as to give guidance to manufacturers of electrical appliances and electronic equipment and to ensure replacement of fuse resistors with particular overcurrent protection by those of similar dimensions and characteristics; c) to establish uniform test methods for fuse resistors with particular overcurrent protection, so as to allow verification of the values (for example rated dissipation, functioning characteristic and rated breaking capacity values) specified by the manufacturer. This part of IEC 60127 applies in addition to the requirements of IEC 60127-1. This first edition of IEC 60127-8 cancels and replaces IEC PAS 60127-8:2014. This international standard is to be used in conjunction with IEC 60127-1. Keywords: Miniature Fuses, Fuse-Resistors, Overcurrent Protection
