The adjustable thermal-magnetic trip range spans 150 A minimum to 1 200 A maximum, so the same frame covers a wide band of settings; you set the actual pickup to match the load. At 240 V it clears 187 kA — that's utility-grade fault current, typical for a service entrance or a transformer secondary. At 415 V and 440 V it still handles 121 kA, and at 500 V it's 75.6 kA.
Built-in auxiliaries and release — what's in the can
The UVR means the breaker trips if control voltage drops — standard for emergency-stop circuits or undervoltage protection on motor feeders. The two aux switches give you status feedback (open/closed) to a PLC or a panel lamp without adding external limit switches. Mounts on a standard DIN rail or direct panel; the 105 mm width (4.13 in) and 86 mm depth (3.39 in) mean it fits a standard distribution board cutout.
