What this MCCB delivers
Its breaking capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — numbers that tell you it handles high-fault installations without cascading upstream.
Thermal derating — the real-world current
At 55 °C it drops to 96 A, at 60 °C to 94 A, at 65 °C to 92 A, and at 70 °C to 90 A. The TM240 release is a fixed thermal-magnetic unit, so no field adjustment on the thermal curve; the breaker trips on its factory-set characteristic.
Panel fit and auxiliary hardware
The breaker occupies 76.2 mm width (roughly 3 inches), 130 mm height, and 70 mm depth — a standard MCCB footprint that drops into most SENTRON distribution blocks.
