It carries a continuous current Iu of 63 A at 40 °C ambient, with a thermal-magnetic TM240 overcurrent release. The interrupting ratings hit 121 kA at 240 V AC and 75.6 kA at 415 V AC — enough for high-fault utility feeds or transformer secondaries. The 3-pole body includes an undervoltage release (UVR) and a 2-auxiliary + 1 trip-alarm switch HQ contact block, so it drops the load on loss of control voltage and signals the trip remotely.
