Zero clearance needed at the sides or back; the 45 mm wide footprint leaves room for a contactor alongside in a standard motor starter stack. The 5 A continuous rating at 690 V maximum sets the motor FLA it can protect — size it to the motor nameplate, not the breaker's maximum. The 100,000-cycle mechanical endurance is the rated life of the main contacts under normal switching — expect fewer cycles if it's used as a disconnect under load regularly.","metaTitle":"Siemens SIRIUS 3RV1021-1FA10-ZW95 Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-1FA10-ZW95 motor protection circuit breaker. 5 A continuous, Class 10 trip, 100 kA breaking at 400 V AC.
