Its interrupting capacity reaches 75.6 kA at 240 V, tapering to 52.5 kA at 415 V and 11.9 kA at 690 V — so it handles high-fault utility feeds without cascading upstream.
Rated current holds flat at 63 A from 40 °C to 50 °C ambient, then derates gradually to 58 A at 70 °C (–). The 75.6 kA SCCR at 240 V is the figure that governs fault withstand for most North American commercial services; at 415 V (52.5 kA,) it still clears heavy industrial faults.

The 130 mm height leaves room for cable glands above. No communication module, so it's a straight electromechanical breaker — no bus address to set, no firmware to match.
