Rated 63 A continuously from 40 °C up to 70 °C without derating, it handles the full load current of a typical 30–37 kW motor at 400 V without needing to oversize the frame. Breaking capacity reaches 330 kA at 240 V AC and 242 kA at 415/440 V, dropping to 3.7 kA at 690 V — the high 240 V figure suits low-voltage distribution where fault currents can be extreme, while the 415 V rating still covers most industrial motor branch circuits. The 3-pole construction matches three-phase motor feeds.
Auxiliary and trip options
The auxiliary contacts let a PLC or DCS confirm breaker position and trip status without extra interface relays. The trip indicator and voltage trigger are built in, so a downstream controller sees exactly when the breaker has operated on fault.
