Siemens 3RV1011-1EA10 Combination Motor Controller Circuit Breaker

Siemens 3RV1011-1EA10 is a three-pole Sirius motor protection circuit breaker (MPCB) in size S00, designed for DIN-rail mounting in control panels and combining overload protection with short‑circuit protection for small motors. It provides a 4 A rated current (2.8–4 A range) and operates on 220–690 V AC, enabling motor protection for machines around 1.5 kW at common voltages. The device offers a short-circuit current rating up to 50 kA at 400 V AC and features a Class 10 A‑release trip characteristic, making it suitable for reliable motor protection in compact panel installations. As part of the Sirius 3RV family, this MPCB is a compact, integrated protection device intended for motor circuits that require both circuit breaking and overload protection in a single unit.
