Low-voltage switchgear and controlgear - Part 4-1: Contactors and motor-starters - Electromechanical contactors and motor-starters
This part of IEC 60947 is applicable to the following equipment:
– electromechanical contactors and starters including motor protective switching device
(MPSD);
– actuators of contactor relays;
– contacts dedicated exclusively to the coil circuit of this contactor or this contactor relay;
– dedicated accessories (e.g. dedicated wiring, dedicated latch accessory);
intended to be connected to distribution circuits, motors circuits and other load circuits, the
rated voltage of which does not exceed 1 000 V AC or 1 500 V DC.
This document covers also the assessment procedure for electromechanical overload
protection used in safety applications such as protecting a motor located in explosive
atmosphere from the outside atmosphere: See Annex L.
