The 4-pole construction makes it the right choice for three-phase plus neutral applications where you need coordinated overcurrent and short-circuit protection on all four paths. Interrupting capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 11.9 kA at 690 V.
Above that it steps down: 488 A at 55 °C, 476 A at 60 °C, 464 A at 65 °C, and 452 A at 70 °C. If your panel ambient runs 55 °C — common in sealed enclosures near ovens or in hot climates — you lose 12 A, not a showstopper for most loads. Dimensions: 184 mm wide, 248 mm tall, 110 mm deep.
Panel wireman's fit check — 184 mm width, 4-pole, no comms
If your spec calls for remote tripping or power monitoring, you'll need the accessory slot populated separately. The trip indicator is absent, so visual confirmation of a trip requires checking the handle position or adding an auxiliary contact. Ground-fault monitoring is not built in. For GF protection on the feeder, you'd add an external ground-fault relay and shunt trip, or step up to the 3VA with electronic release. This version is for straightforward line protection where the downstream devices handle ground-fault coordination.
