Description
Applies to a.c. contactors and/or contactor-based motor-starters designed for indoor installation and operation at frequencies up to and including 60 Hz on systems having voltages above 1000 V but not exceeding 12000 V. In particular applies to three-pole contactors and starters for use in three-phase systems and single-pole contactors and starters for use in single-phase systems. Contactors and/or starters dealt with in this Standard are not normally designed to interrupt short-circuit currents. This Standard is also applicable to the operating devices of contactors and to their auxiliary equipment. This Standard is identical with and has been reproduced from IEC 60470:2000.
