Its breaking capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — enough headroom for most industrial distribution panels where fault currents are high. The 63 A rating holds steady up to 50 °C ambient; above that it derates gradually to 56.7 A at 70 °C.
The TM240 overcurrent release is a thermal-magnetic type — the thermal element handles overloads (adjustable response time up to 1 s), and the magnetic element handles short circuits. No undervoltage release, no shunt trip, no ground-fault monitoring built in; if you need those, you add auxiliary releases externally. Rated insulation voltage is 800 V, so the breaker can be used in 690 V line-to-line systems (the 10.5 kA breaking capacity at 690 V confirms that). The 2 HQ auxiliary switches provide status feedback for remote monitoring or PLC inputs.
The 76.2 mm width (roughly 3 inches) fits standard MCCB slots in most distribution boards.
