Product details

Motor protection circuit breaker, S0 frame, 2.8–4 A

The Siemens 3RV2021-1EA20-Z X95 is a SIRIUS 3RV2 motor starter protector in the size S0 frame, with a Class 10 thermal overload release adjustable from 2.8 to 4 A and a fixed magnetic short-circuit release set at 52 A. The spring-type terminals reduce wiring time and hold torque without re-tightening, which matters when the panel is built in a batch and every second counts. Standard switching capacity covers most motor branch circuits up to the rated breaking capacity — no need to upsize the frame for typical pump, fan, or conveyor loads.
