IEC 60534-2-1:2011/COR1:2015
(Corrigendum)Corrigendum 1 - Industrial-process control valves - Part 2-1: Flow capacity - Sizing equations for fluid flow under installed conditions
General Information
- Abstract
Applies to portable devices consisting of a plug, a residual current device (RCD) and one or more socket-outlets or a provision for connection. They do not incorporate overcurrent protection. They are intended for single-phase circuits for rated currents not exceeding 16 A for rated voltages not exceeding 250 V a.c., or for rated current not exceeding 32 A for rated voltages not exceeding 130 V a.c. to earth.
