The interrupting ratings climb to 121 kA at 240 V and 75.6 kA at 415 V, which covers most industrial service-entrance and feeder applications where high fault current is expected.
Interrupting capacity and thermal derating
At 415 V the breaker clears 75.6 kA symmetrical — enough for a main breaker in a 2000 A panel fed by a medium-voltage transformer. The continuous current holds flat at 160 A up to 50 °C, then drops to 153.6 A at 55 °C and 144 A at 70 °C. That derating curve means you can push it to 160 A in a ventilated 50 °C enclosure; above that, the TM240 release needs headroom.
Built-in undervoltage release and auxiliary contacts
No communication function or phase-failure detection on board; this is a pure protection device.
The breaker measures 76.2 mm wide by 130 mm tall by 70 mm deep — fits a standard 3-pole MCCB slot in a SENTRON distribution panel or a generic enclosure with DIN-rail or screw-mount backplate.
Mechanical endurance is 15 000 operations — typical for a fixed-mounted MCCB in a panel that sees infrequent switching. The trip indicator is present, giving a visual flag when the breaker has tripped on fault.
