Line protection MCCB with TM240 release
The TM240 thermal-magnetic release provides fixed overload and short-circuit protection curves; no voltage trigger is fitted. Breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — figures that govern the available fault current the breaker can safely interrupt without upstream coordination failure. No communication function, phase failure detection, ground fault monitoring, or other measurement function is built in.
Above that, derating applies: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C.
