SIRIUS circuit breaker for starter combinations
It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a width of 55 mm and depth of 149 mm, fitting standard panel layouts without surprises. Rated for a voltage range of 20 to 690 V, its interrupting capacity hits 100 kA at 240 V, 30 kA at 400 V, and 3 kA at 690 V — figures that tell you this breaker handles high-fault-current scenarios at lower voltages while still clearing faults at 690 V. The 30 kA at 400 V is the number most panel builders will check first for industrial distribution.
Required clearances: 50 mm upwards, 50 mm downwards, 10 mm at the side, and 0 mm forwards and backwards — so you can pack it tight against the backplane and adjacent devices, as long as you leave breathing room above and below for arc-quenching and thermal dissipation.
