Product details

Motor protection breaker for small loads

Rated operating current is 0.8 A at AC-3 duty (400 V), delivering 180 W of motor power at that voltage — sized for fractional-horsepower loads like small pumps, fans, and conveyors. The thermal overload release is field-adjustable from 0.55 A to 0.8 A, letting you dial in the exact FLA of the connected motor without swapping the breaker body.

Trip class and short-circuit protection

The magnetic short-circuit release is fixed at 10 A, providing instantaneous interruption for hard faults while letting the overload element handle sustained overcurrents.

Any mounting position is permitted. Clearance requirements: 20 mm upwards and downwards, 9 mm to the side, zero forwards and backwards. The 20 mm vertical gap is the minimum free air space needed above and below the breaker for arc quenching and heat dissipation.

Frequently asked questions

What are the clearance requirements for 3RV1011-0HA10-ZI45?

Requires 20 mm upwards, 20 mm downwards, and 9 mm to the side. Zero clearance needed forwards or backwards.

Will 3RV1011-0HA10-ZI45 drop into a panel specified for 3RV1011-0HA10?

Yes. The -ZI45 variant shares the same S00 frame, DIN rail mounting, screw terminals, and 45×90×75 mm footprint as the base 3RV1011-0HA10. No rewiring or panel modification needed.
