| Design Of The Product | For motor protection |
Clearance requirements: 50 mm upwards and downwards, 30 mm at the sides, and zero clearance forwards and backwards. The unit is rated for a maximum of 15 operating cycles per hour under AC-3 and AC-3e duty.
For coordination with upstream fuses, the recommended gL/gG ratings are 25 A at 400 V, 32 A at 500 V, and 25 A at 690 V. Horsepower ratings span from 0.1 hp at 110/120 V up to 2 hp at 460/480 V and 575/600 V. The breaker does not include ground fault detection.
It is a trip class 10 motor protection circuit breaker rated for 20-690 V, with a short-circuit breaking capacity of 100 kA at 400 V. It includes phase failure detection and uses spring-loaded terminals.
Clearances required: 50 mm upwards and downwards, 30 mm at the sides, and zero clearance forwards and backwards. It can be mounted in any position on 35 mm DIN rail.
Recommended gL/gG fuses: 25 A at 400 V, 32 A at 500 V, and 25 A at 690 V.
