Product details

Motor Protection Circuit Breaker with Overload Relay Function

The Siemens 3RV2131-4DA10 is a SIRIUS circuit breaker designed for motor protection with an integrated overload relay function, combining short-circuit and overload protection in one device for induction motor branch circuits.

Terminals accept 2× (1–25 mm²) or 1× (1–35 mm²) solid or stranded copper, with M6 screw-type connections for the main circuit.

Environmental and Electrical Ratings

Switching frequency at AC-3 duty (motor starting) is rated at a maximum of 15 operations per hour, adequate for pumps, fans, and conveyors that cycle infrequently.
