This part of IEC 60947 applies to AC and DC contactors and AC motor-starters whose main contacts are intended to be connected to circuits the rated voltage of which does not exceed 1000 V a.c. or 1500 V d.c. In this context, this standard gives requirements for contactors associated with overload and/or short-circuit protective devices; starters associated with separate short-circuit protective devices and/or with separate short-circuit and integrated overload protective devices and contactors or starters combined, under specified conditions, with their own short-circuit protective devices. Such combinations, e.g. combination starters or protected starters are rated as units.
