Descriere

PM12 AC contactors for load currents from 10 to up 63 A (AC-3) are intended for actuating, shutting down and reversing of asynchronous electric motors equipped with a short-circuited rotor for the applied voltage limited to 660 V (AC-3 application category). They can be also used for remote control of lighting, heating circuits and various low-inductance loads (AC-1 application category). All unit types per load currents limited to up 40 A have a single group of auxiliary NO or NC contacts. Types per load currents exceeding 63 A have two contact groups (NO and NC).The PM12 contactor is a well-known brand in the market.
