UL 60947-4-1

YEAR FILE EDITION SCAME

American Standard

 

Contents
(courtesy UL)

This part of IEC 60947 applies to the types of equipment listed in 1.1.1 and 1.1.2 whose main contacts are intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.
Starters and/or contactors dealt with in this standard are not normally designed to interrupt short circuit currents.
Therefore, suitable short-circuit protection (see 9.3.4) forms part of the installation but not necessarily of the contactor or the starter.
