Siemens 3RV2011-1FA10 Motor Protection Circuit Breaker 3P 5A

The Siemens 3RV2011-1FA10 is a 3-pole SIRIUS motor protection circuit breaker, size S00, with an adjustable thermal overload release of 3.5...5 A and CLASS 10 trip characteristics. It combines thermal overload protection (ANSI 49) with magnetic short-circuit tripping via an instantaneous N release at 65 A. Breaking capacity reaches 100 kA at voltages up to 500 V AC, and 6 kA at 690 V AC.
