Siemens 3RV2011-1EA15 Motor Protection Circuit Breaker

Siemens 3RV2011-1EA15 is a three‑pole motor protection circuit breaker in the S00 frame of the Sirius 3RV2 family, designed for direct motor protection in control panels and compact starters. It pairs thermal overload protection with instantaneous short‑circuit release, offering an adjustable A‑release (thermal) setting from 2.8 to 4 A and an instantaneous N release rated at 52 A, with a voltage range of 220–690 V AC and IP20 front protection for safe DIN‑rail mounting. The device features screw‑terminal main connections, a removable terminal for auxiliary and control circuits, and a transverse auxiliary switch with 1 normally open and 1 normally closed contact for signaling and interlocking. Trip behavior includes phase disturbance recognition, supporting reliable protection for motors subject to voltage imbalances, while the unit is rated for substantial mechanical life (up to about 100,000 switching cycles). Suitable for small industrial motors up to roughly 1.5 kW at typical voltages, this compact motor protection circuit breaker provides integrated overload and short‑circuit protection in a single, DIN‑rail‑mountable module.
