Rated breaking capacity sits at 25 kA at 400 V, backed by 63 A gL/gG fuse coordination at the same voltage. That SCCR handles most industrial transformer secondary faults without cascading upstream.
Width is 45 mm, depth 97 mm, height 97 mm — a standard 45 mm modular device that snaps onto 35 mm DIN rail per DIN EN 60715. Screw and snap-on mounting means it locks in place without tools and releases with a screwdriver push. Clearance: 50 mm upwards, 50 mm downwards, 30 mm at the side. Mounting position is any orientation. Main contact terminals accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²) — screw terminals, M4 thread. The 45 mm width keeps the per-feeder density tight on a DIN rail; you can pack multiple units side by side within the clearance envelope.
Operating conditions
Rated operational voltage spans 20 to 690 V. Maximum switching frequency under AC-3 or AC-3e duty is 15 operations per hour. Auxiliary contact ratings: 1 A at 24 V, 0.5 A at 120/125/230 V, 0.15 A at 60 V. The auxiliary contact block uses the same M4 screw terminals as the main contacts.
