Product details

Breaking capacity and selectivity headroom

The interrupting ratings climb steeply with voltage: 121 kA at 240 V, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V.

Thermal derating — the real-world current

Above that it steps down: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C. The TM240 release is calibrated for this curve; no separate derating factor to calculate.

The two factory-fitted auxiliary switches (HQ) share the same housing; no add-on module needed for status feedback. The undervoltage release is wired separately — verify polarity on the coil before energizing.
