Reversing contactor PMA-3400 UHL4 B 40A cat. 380V AC 4NO+4NC IP00 with RTT-141 relay 28.0-40.0A Elektrotekhnik ET000040

PMA-3000 series electromagnetic contactors are intended for use in stationary installations for remote starting, stopping, and reversing of three-phase squirrel-cage induction motors with a voltage up to 660 V AC 50 and 60 Hz. When thermal relays are present, the contactor protects the controlled electric motors from: * overload; * currents arising from the loss of one of the phases; * phase asymmetry. * Contactors are characterized by high mechanical and switching wear resistance, which ensures a long service life even under intensive operating conditions; * Complies with GOST requirements for industrial equipment, ensuring high reliability of operation; * Absence of noise and increased reliability of operation; * Simple design and high reliability, proven by operating time.
