Siemens 3RV10110CA15 Motor Protection Circuit Breaker

Siemens 3RV10110CA15 is a S00‑size motor protection circuit breaker from the SIRIUS 3RV1 family, designed to protect small motors in control panels by interrupting power during overloads and short circuits and providing safe isolation. It combines a thermal overload release adjustable from 0.18 to 0.25 A with a magnetic (N) release of 3.3 A, delivering Class 10 motor protection for AC‑3 circuits and featuring a transverse auxiliary switch with 1 normally open and 1 normally closed contact. The unit uses screw terminals, is rated for up to 690 V operation, and offers a high breaking capacity (Icu up to 100 kA at 240–690 V) for reliable motor protection in compact installations. Its compact frame and integrated signaling make it well suited for motor protection and safe isolation in space‑constrained control panels.
