Three poles, designed specifically for motor protection duty, with built-in phase failure detection. Breaking capacity is the real selector here: 330 kA at 240 V, 242 kA at 415 V, dropping to 9 kA at 690 V. On a 400 V class panel — typical for industrial motor control centers — the 242 kA SCCR gives ample headroom for high-fault installations like large transformer secondaries or utility tie points. That 110 mm depth fits standard enclosures.
Active status means lead times are predictable. Power loss is 63.5 W maximum — account for that heat in enclosure thermal calculations.
Rated insulation voltage 800 V — the internal clearances and creepage are sized for 600 V class systems, so it's fine on 480 V and 600 V lineups. If you need those functions, they'd be external or on a different variant. No trip indicator and no voltage trigger. The short-time withstand rating is limited to 5 kA for 1 second — relevant for selective coordination studies: downstream devices must clear faster than that to avoid stressing the main breaker.
