Its breaking capacity reaches 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V — figures that define the fault-clearing capability at the point of installation, not the running load.
The 220 kA at 240 V and 154 kA at 415 V ratings mean this MCCB can interrupt very high fault currents without upstream coordination failure — critical for transformer secondaries or bus-tie positions where available fault current exceeds 100 kA. The TM240 release is fixed-thermal, fixed-magnetic; no interchangeable trip units. The thermal derating curve is flat at 25 A from 40 °C through 50 °C, then drops to 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C.
Undervoltage release and auxiliary options
No auxiliary contacts or shunt trip are fitted on this unit; those would need to be added externally if required.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits most SENTRON panelboards and distribution blocks.
