AS 60470 – High-voltage alternating current contactors and contactor-based motor starters

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 volt 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.
