Product details

Motor-protective circuit breaker for a 0.09 kW motor branch

The Siemens SIRIUS 3RV1021-0DA10-ZW96 is a 3-pole motor-protective circuit breaker rated at 0.32 A continuous current, sized for a 0.09 kW motor at 400 V AC.

DIN-rail integration and panel envelope

Any mounting position is permitted, and zero clearance is required at the rear or sides, so it can be packed tightly against other devices on the rail. IP20 on the front means protected against finger contact — suitable for enclosed panel installation, not for exposed outdoor use.
