Siemens 3RH1140-2AF00 Contactor

Siemens 3RH1140-2AF00 Contactor Relay is a SIRIUS four normally open (4 NO) contactor with a 110 V AC coil (50 Hz) in the compact S00 frame, designed to switch AC loads up to 600 VAC at up to 10 A. It uses Cage Clamp terminals for secure wiring and carries a 690 V insulation rating with IP20 protection on the front. The device operates from -25 to +60 C and up to 2,000 m above sea level, and delivers a mechanical life of about 30 million switching cycles with a 6 kV surge/impulse voltage rating. This configuration suits control panels and automation circuits that require multiple normally open contacts controlled by a 110 V AC coil, offering robust insulation and durable performance in standard industrial environments.
