The adjustable thermal-magnetic trip unit covers 150 A to 1 200 A, so you set the actual protection threshold to match the downstream load, not the breaker's frame size.
Breaking capacity varies with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. At typical 400 V-class industrial feeds (415 V or 440 V), the 121 kA rating handles high-fault scenarios like large transformer secondaries or motor-control-center buswork.
Built-in auxiliaries and communication
It also includes a communication function for remote monitoring or signaling.
Maximum power loss is 12.5 W, manageable in enclosed panels with basic ventilation.
