It's a 3-pole unit rated at 63 A continuous current, with no derating needed from 40 °C up through 70 °C — the full 63 A holds across that entire ambient range, which simplifies panel design in warm enclosures. The interrupting capacity hits 187 kA at 240 VAC, 121 kA at 415/440 V, and still delivers 75.6 kA at 500 V — numbers that give real headroom for high-fault installations.
That flat derating curve is unusual; many MCCBs start stepping down above 40 °C. The adjustable thermal-magnetic trip range spans 95 A minimum to 756 A maximum, so this breaker can be set to protect loads well below its frame rating if needed.
The shunt trip (STL) release is built in, so remote tripping from a safety circuit or E-stop is wired directly. Communication function is onboard, meaning it can report status and accept commands over the SENTRON communication bus without an external module.
