Siemens 3RV2011-1JA10 Motor Starter Protection

Siemens 3RV2011-1JA10 is a SIRIUS 3RV2 motor starter protector (circuit breaker) engineered for motor protection and designed for DIN-rail mounting in size S00. This three-pole device combines thermal overload protection with a Class 10 release and an adjustable A-release in the 7–10 A range, complemented by a magnetic N-release for higher fault currents up to 130 A. Rated for operation up to 690 V AC and featuring screw terminals, it is suitable for compact motor circuits within control panels and aligns with the SIRIUS 3RV2 family’s approach to motor protection in a single, space-saving unit. In typical industrial applications, it protects small to mid-size three-phase motors in equipment such as conveyors, pumps, fans, and machine tools, providing both overload protection and short-circuit disconnection while enabling straightforward integration with DIN-rail mounted control gear.
