Siemens 3RV2011-1AA10 SIRIUS Motor Protection Circuit Breaker 1.6A 3P

The Siemens 3RV2011-1AA10 is a SIRIUS 3RV2 series motor protection circuit breaker in size S00 for 3-phase AC motor applications. It combines adjustable thermal overload release from 1.1 to 1.6 A (CLASS 10) with magnetic instantaneous short-circuit protection at 21 A. Ultimate breaking capacity (Icu) and service breaking capacity (Ics) both reach 100 kA at all rated voltages from 240 V to 690 V AC.
