Siemens 3RV1011 0CA15 Manual Motor Protector Breaker

Siemens 3RV1011-0CA15 is a compact S00-frame motor protection circuit breaker that provides integrated thermal overload and magnetic protection for small motors in single- and three-phase circuits, designed for panel-mount installations within control cabinets and automation enclosures up to 690 V AC or DC. This three-pole device carries a Class 10 release with an A-release current of 0.18 to 0.25 A and a magnetic (N-release) setting of 3.3 A, is wired via screw terminals, and includes a transverse auxiliary switch (1 NO + 1 NC) to support signaling and control wiring. As part of the Siemens Sirius 3RV1 family, it is engineered for reliable motor protection in compact installations, offering standard switching capacity and a 3-pole arrangement that helps protect against overloads and short circuits in demanding panel environments. Typical applications involve motor protection in control panels and automation enclosures where space is at a premium, and where a 690 V-rated protector with the 0.18–0.25 A A-release and 3.3 A N-release provides precise protection without unnecessary trips.
