Siemens 3RV2011-1EA10 Motor Protection Circuit Breaker

Siemens 3RV2011-1EA10 is a three‑pole motor protection circuit breaker (MPCB) in the S00 size from the SIRIUS 3RV2 family, designed to protect small three‑phase motors and mount on a DIN rail. It provides overload protection with a Class 10 A trip and a selectable current release of 2.8 to 4 A, enabling tailored motor protection for the application. The device is rated for up to 690 V AC and operates at 50/60 Hz, with IP20 protection on the front and 6 kV surge resistance, making it suitable for typical industrial environments. Main and control wiring use screw terminals, and the compact S00 form factor supports integration in compact motor control panels. Common applications include protecting motors in conveyors, pumps, fans, and machine tools within the 220–690 VAC range, particularly for motors around ~1.5 kW as referenced in typical catalog listings.
