Overview

EN 60947-5-5:1997/A1:2005 (CLC) is the European adoption of IEC 60947-5-5 amendment A1, and specifies requirements for electrical emergency stop devices with mechanical latching function used in low‑voltage switchgear and controlgear. This amendment (approved 2005) updates EN 60947-5-5:1997 and incorporates the corrigendum issued July 2007. The document is intended to harmonize performance, testing and application criteria across CENELEC member states for emergency stop control circuit devices.

Key topics and requirements

• Scope and purpose: Defines the functional category for emergency stop devices that mechanically latch in the stop position and form part of control circuits in low‑voltage equipment.
• Design and performance: Addresses essential characteristics such as reliable latching, reset behaviour and integration into control circuits (general principles rather than specific numeric values are in the IEC text).
• Environmental and mechanical testing: References established test suites (IEC 60068 series) for cold, dry heat, vibration, shock, salt mist and damp heat to verify durability and suitability for intended environments.
• Human‑machine interface and marking: Cross‑references IEC 60073 (coding for indicators and actuators) and EN/IEC guidance on signalling (IEC 61310-1), ensuring clear identification and ergonomic operation.
• Machine safety alignment: Linked to ISO 13850 (principles for emergency stop) and IEC 60204-1 (safety of machinery - electrical equipment), supporting coordinated safety strategies for machinery control.
• Normative references and annex: Amendment adds Annex ZA and updates normative references (lists of indispensable documents for application and harmonized European publications).

Applications

• Design and manufacture of industrial control panels, machine control systems and safety circuits where an emergency stop with mechanical latching is required.
• Safety engineers specifying emergency stop devices to meet harmonized EU practice for low‑voltage installations.
• Test laboratories and certification bodies evaluating compliance with IEC/EN requirements for emergency stop devices.
• OEMs, machine builders and integrators using standardized emergency stop devices to ensure interoperability and safety compliance across European markets.

Related standards (key references)

• IEC 60947-5-5 / EN 60947-5-5 (base standard)
• IEC 60947-5-1 (electromechanical control devices)
• IEC 60068 series (environmental testing)
• IEC 60204-1 (safety of machinery - electrical equipment)
• ISO 13850 (emergency stop principles)
• IEC 60073, IEC 61310-1 (marking, indicators and actuation)

EN 60947-5-5:1997/A1:2005 is essential for professionals specifying or certifying emergency stop devices in low‑voltage control systems, providing harmonized technical and testing context to support safe, compliant machinery design.
