Siemens 3RV2111-0BA10 Motor Protection Circuit Breaker

Siemens 3RV2111-0BA10 is a SIRIUS 3RV2 motor protection circuit breaker (MPCB) in size S00, built to protect small motors from overload and short circuits in AC applications. It is rated for a nominal current of 2.6 A and supports operation across a voltage range of 220–690 VAC. The device combines an overload relay (A-release) with a short-circuit release (N-release) to provide motor protection in a compact DIN-rail mount package with screw-terminal connections. As a Class 10 protective device, it is designed to disconnect swiftly under overload or fault conditions to safeguard motors and drive systems in control panels. Typical applications include protection for small motors in machinery, conveyors, pumps, and fans, where compact Siemens protection and compatibility with the SIRIUS 3RV2 family are advantageous.
