Breaking capacity hits 75.6 kA at 240 V, tapering to 11.9 kA at 690 V — enough for most industrial distribution panels downstream of a transformer. The TM240 thermal-magnetic release handles overload and short-circuit without an external trip unit.
Breaking capacity and derating
The 75.6 kA at 240 V is the headline number, but the curve matters: 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Thermal derating stays flat at 100 A from 40 °C to 50 °C, then drops to 91 A at 70 °C.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. The built-in auxiliary switch pack (2 HP) provides status feedback without a separate accessory module.
