Product details

Class 10 trip — protects the motor winding, not the feeder

Rated at 40 A continuous, the 3RV2041-4FA10 handles motor full-load currents up to that value. The SCCR (short-circuit current rating) of the downstream contactor and overload relay is coordinated with this breaker; the 3RV2041 limits the let-through energy so the contactor survives a fault.

Screw terminals, DIN rail, any position — panel integration

The solid/stranded wire range is 2x (2.5... 16 mm²) for the power circuit, with a larger range of 2x (2.5... 50 mm²) or 1x (10... 70 mm²) available for the load side — sized to handle the full 40 A without derating. The control circuit terminals accept 2x (2.5... 16 mm²) solid or stranded. The dimensions are 70 mm wide, 165 mm high, 176 mm deep.

Frequently asked questions

What is the ampere rating of Siemens 3RV2041-4FA10?

The 3RV2041-4FA10 is rated at 40 A continuous. This is the maximum full-load motor current it is designed to protect. The thermal-magnetic trip mechanism allows adjustment of the overload setting within a range around this value.

Does 3RV2041-4FA10 have screw terminals?

Yes, the main current circuit uses screw-type terminals. The wire range is 2x (2.5... 16 mm²) solid or stranded for the power side, with a larger range available for the load side.

Can 3RV2041-4FA10 be mounted on DIN rail?

Yes. It mounts via screw or snap-on onto a 35 mm DIN rail per DIN EN 60715. The mounting position is any orientation.
