Siemens 3RV2011-0JA10 Motor Protection Circuit Breaker

Siemens 3RV2011-0JA10 is a S00-size motor protection circuit breaker from the SIRIUS 3RV2 family, designed to protect small motors in 220–690 V AC systems. This compact DIN-rail‑mountable device combines overload protection and short-circuit protection in a single unit and is specified for motor protection with a rated power of 0.25 kW for small motors. The thermal-magnetic trip system uses an A-release rated 0.7–1 A and an N-release 13 A, with a continuous current rating of 1 A, Class 10 overload protection; it is built to handle frequent starting and motor loading. The breaker is rated for up to 690 V AC, with IP20 protection on the front and at the terminals, and it supports surge resistance up to 6 kV. Mechanical and electrical endurance are specified at around 100,000 switching cycles, making it suitable for automatic control panels requiring reliable motor protection in compact spaces. Suitable for Siemens automation environments, 3RV2011-0JA10 integrates with standard DIN rail hardware and complements other SIRIUS devices for centralized motor protection in machines such as conveyors, fans, and pumps.
