For a panel fed from a transformer rated 1,000 kVA or larger, that is enough headroom to avoid cascading failures upstream. At 690 V it still clears 4 kA, so it works on 690 V line-fed motors too, though the fault current available at that voltage must be verified against the panel's SCCR. The thermal-magnetic trip is Class 10, which matches the acceleration curve of a standard NEMA Design B or IEC squirrel-cage motor. If the motor takes longer than 10 seconds to start (high-inertia loads like fans or centrifuges), you need a Class 20 or Class 30 device — this one will nuisance-trip on those applications. The width is 55 mm, which is a standard 3-module footprint on a DIN rail — one-for-one swap with most Siemens 3RV2 series breakers. Depth is 149 mm, which matters for enclosure depth clearance. Terminals are screw-type, accepting up to 2× 35 mm² or 1× 50 mm² solid/stranded. Main contact studs are M6.
