| Poznámka vo Vestníku: | |
| Predmet normy: | IEC 60947-4-1:2023 is applicable to the following equipment: - electromechanical contactors and starters including motor protective switching devices (MPSD and IMPSD); - actuators of contactor relays; - contacts dedicated exclusively to the coil circuit of the contactor or the 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 fifth edition cancels and replaces the fourth edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) objective in the scope; b) instantaneous only motor protective switching device IMPSD (3.5.33); c) kinds of equipment (5.2.1); d) methods of overload protection of motors (5.2.6); e) adoption of the AC-7d from IEC 61095:2023 (in 5.4.2); f) separately ... |
