Design Of The ProductFor motor protection

Product details

It delivers a 50 kA breaking capacity at 400 V, 10 kA at 500 V, and 5 kA at 690 V — figures that tell you it can interrupt a bolted fault at the motor terminals without needing an upstream current-limiting fuse in most industrial distribution panels. Rated continuous current is 25 A at 480 V and 25 A at 600 V, so it's sized for a motor nameplate in that range; the 5 hp rating at 230 V confirms the typical light-to-medium duty motor it protects.

DIN Rail Fit and Panel Clearances

Auxiliary Contact Ratings and Control Circuit Load

The integrated auxiliary contact switches 1 A at 24 V, 0.15 A at 60 V, and 0.5 A at 230 V — enough for a PLC digital input or a contactor coil, but not for a heavy solenoid directly. Rated insulation voltage spans 20 to 690 V, covering most low-voltage motor control circuits.

Environmental and Installation Notes

Main contact terminals accept M6 bolts; control-circuit wiring takes 2x 0.5 to 2.5 mm² solid or stranded.

Frequently asked questions

What clearance is needed around 3RV2032-4DA15 in a panel?

50 mm above and below the device, 10 mm at the sides.

Does 3RV2032-4DA15 include phase failure detection?

Yes, phase failure detection is built in; ground fault detection is not included.
