Siemens Industry, Inc. 3RV2011-1KA20 Circuit Breaker

Siemens 3RV2011-1KA20 is a motor-protection circuit-breaker in the S00 frame from the SIRIUS 3RV2 family, designed to protect small motors in AC circuits up to 690 V. It combines a thermal release (A-Release) with a current range of 9–12 A and a magnetic release (N-Release) rated at 163 A, delivering Class 10 trip performance to meet standard motor-protection requirements. The device uses a spring-type terminal for secure connections and provides standard switching capacity for motor-control duties. With a maximum breaking capacity up to 100 kA, it can protect single-motor circuits and integrate with Siemens' SIRIUS motor-protection lineup.
