It carries a TM220 thermal-magnetic overcurrent release — that's a fixed thermal trip with an adjustable magnetic pickup, so you set the short-circuit threshold to coordinate with downstream devices without swapping the breaker body. Interrupting capacity hits 76 kA at 240 V AC, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V, giving you selectivity headroom across common industrial voltages.
Thermal derating and real-world ampacity
Above that, the breaker derates linearly: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C.
It's a standard panel-mount footprint — no DIN-rail clip on this frame, so you bolt it directly to the mounting plate or into a distribution block. The IP40 front protection means it's splash-safe in the panel but not rated for washdown; keep it behind a sealed enclosure door in wet environments.
