Breaking capacity and backup fusing
Rated breaking capacity hits 100 kA at 400 V and 500 V, dropping to 10 kA at 690 V. For installations needing higher fault current discrimination, the backup fuse ratings are gL/gG 25 A at 400 V and 500 V, and gL/gG 20 A at 690 V.
Width is 45 mm, depth 97 mm, height 97 mm. Mounting position any — no derating for horizontal or vertical orientation. Clearance requirements: 50 mm upwards and downwards, 30 mm at the side, 0 mm forwards and backwards. That zero forwards clearance means it can sit flush against a gland plate or back panel without needing breathing room on the front face.
