Electromagnetic Contactor PM12-315200 UHL4 B 315A 220V/50Hz AC 4NO+2NC IP00 non-reversing with relay PTT12-400 200-300A Elektrotekhnik ET011781

PM12 series electromagnetic contactors are designed for remote starting by direct connection to the network, stopping, and reversing of three-phase asynchronous squirrel-cage motors with a voltage of up to 660 V AC 50 and 60 Hz. When equipped with thermal relays, the contactor provides protection for the controlled electric motors against: * overload; * currents arising from a phase break; * phase asymmetry. * Contactors feature high mechanical and switching endurance, ensuring a long service life even under intensive operation; * Complies with GOST requirements for industrial-grade equipment, ensuring high reliability of operation; * Absence of noise and increased operational reliability; * Simple design and high reliability, proven by years of operation.
