It's the kind of part that keeps a paper machine running — if this trips cleanly, you find the root cause instead of chasing a cooked motor on a Saturday night. That's a common failure mode in wet environments where a contact or lug corrodes.
Dimensions are 45 mm wide, 90 mm tall, 75 mm deep — that's a standard 2.5-module footprint on the rail, so it slots into any existing SIRIUS or third-party MCC layout without re-drilling the gland plate. Clearance: 20 mm upwards and downwards, 9 mm at the sides, zero forwards and backwards. That's tight enough for a dense panel but leaves room for cable bending radius on the screw terminals. Screw-type terminals accept 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) solid or stranded. Main contact screws are M3.
Environmental range
That covers a mill's electrical room in summer and a frozen warehouse in winter without derating.
