Siemens 3RV1011-1DA10 Molded Case Circuit Breaker

Siemens 3RV1011-1DA10 molded-case circuit breaker (MCCB) in the S00 frame is a motor-protection device from the Sirius 3RV1 family, designed for DIN-rail mounting in control panels and compact motor-circuit protection in automation setups. It combines thermal-magnetic overload protection with Class 10 timing and carries an A-release that is adjustable from 2.2 to 3.2 A, plus an N-release specified at 42 A, with screw-terminal connections and a standard switching capacity. The unit is rated for 220–690 VAC operation and lists a 1.1 kW motor rating, making it suitable for small to mid-size motors in industrial equipment. Typical applications include protection for conveyors, pumps, fans, and machine tools, where a compact, DIN-rail-mounted MCCB with motor-protection capabilities is required.
