Interrupting capacity is 187 kA at 240 V, tapering to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. That 187 kA at 240 V handles high-fault utility feeds or transformer secondaries; the 7.5 kA at 690 V still clears a fault on a 690 V drive bus. Trip time is adjustable between 4 s and 17 s, matching motor start profiles without nuisance trips.
Mounts in a standard panel enclosure — the 138 mm width and 248 mm height fit a typical MCCB cutout. The undervoltage release (UVR) is built in, so no separate coil or monitoring relay is needed for undervoltage protection. Phase failure detection is integrated; no external phase-loss module required. The trip indicator gives a local visual of the breaker state without opening the door.
