Motor protection circuit breaker for the critical path
Dimensional fit and mounting
The cube measures 97 mm high by 97 mm deep by 45 mm wide — that 45 mm width is the same as a standard single-pole MCB footprint, so it fits in a typical motor control center bucket without crowding adjacent devices. Clearance requirements: 50 mm upwards and downwards, 30 mm to the sides, zero forwards or backwards — that's the minimum air gap for arc quenching and thermal dissipation.
Main current circuit uses screw-type terminals sized for M3 screws, accepting 2×(0.75–2.5 mm²) solid or stranded, or a single 4 mm² conductor per clamp. The gL/gG fuse coordination at 400 V and 500 V is 25 A, dropping to 20 A at 690 V — that's the maximum backup fuse rating if you need to coordinate with a downstream short-circuit device.
