It is designed to protect motor branch circuits against short-circuit and overload, with a Trip Class 10 characteristic that trips within 10 seconds at 7.2× the thermal setting, matching standard induction-motor starting profiles.
Width is 45 mm.
Breaking capacity and fuse coordination
The 100 kA breaking capacity at 240 V and 400 V means this breaker can clear a bolted fault at those voltages without needing an upstream fuse for backup protection. At 500 V the rating is still 100 kA; at 690 V it drops to 2 kA. For installations above the interrupting rating, the evidence lists required backup fuses: at 400 V a gL/gG 35 A fuse, at 500 V and 690 V a gL/gG 25 A fuse. At 240 V no backup fuse is required. That is a practical coordination point for panel builders — if your available fault current exceeds 2 kA at 690 V, you must size the upstream fuse accordingly.
Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C. Lifecycle stage is current.
