Motor protection circuit breaker for Class 10 trip curves
Dimensions: 45 mm wide, 90 mm high, 75 mm deep. Clearance requirements: 20 mm upwards, 20 mm downwards, 9 mm at the side, 0 mm forwards and backwards. No extra space needed front or rear — tight-panel friendly.
Operating conditions and ratings
That storage range covers frozen warehouses and hot shipping containers — the part holds up to the temperature extremes a tire-curing plant sees during off-season storage. Rated voltage range is 20 to 690 V. At 690 V, the required backup fuse is gL/gG 4 A; at 240, 400, and 500 V, no backup fuse is required. That simplifies the BOM for 400 V panels — one less component to source. Maximum switching frequency at AC-3 and AC-3e duty is 15 operations per hour. That's typical for a motor starter protecting a pump or conveyor that cycles a few times per hour — not for a high-speed pick-and-place application.
