MCCB for line protection — 40 A, 3-pole, TM220 release
It carries a 40 A continuous rating at 40 °C through 50 °C, with minor derating above that — 39 A at 55–60 °C, 38 A at 65 °C, and 37 A at 70 °C.
Interrupting capacity across voltages
This 3-pole breaker delivers 121 kA interrupting capacity at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The steep drop above 440 V is typical of MCCBs with this frame size — the 11.9 kA at 500/690 V still covers most industrial secondary-distribution fault levels, but verify against your system's available fault current at those voltages.
