Siemens Circuit breaker for motor protection, size S00, 2.2-3.2A Part number 3RV2011-1DA25

Product Overview

The Siemens 3RV2011-1DA25 is a SIRIUS 3RV2 series motor-protection circuit breaker, size S00, designed for protection of small motors and industrial loads. It provides an adjustable overload release range of 2.2 … 3.2 A and features a fixed instantaneous short-circuit release at 42 A. Its compact construction, spring-type terminals and standard switching capacity make it suitable for DIN-rail or panel mounting in control cabinets.
