Product Overview
The Siemens 3RV1021-1EA15 is a SIRIUS series S0-size motor protective circuit breaker. It provides adjustable overload release and short-circuit protection in motor control circuits. The device integrates a transverse auxiliary switch and is intended for manual disconnect and thermal-magnetic protection. It is typically used in motor starter assemblies, control panels, and small machinery applications requiring adjustable current protection and compact design. 3RV1021-1EA15 is now phased out; the preferred successor is SIRIUS 3RV2011-1EA15. 3RV1021-1EA15.
