It carries a continuous current of 80 A at 40 °C with a TM240 thermal-magnetic overcurrent release — the 240 in the release code means the fixed thermal trip is calibrated for 80 A (the frame rating), not a 240 A setting; the TM240 is the release family for this frame size. Rated insulation voltage is 800 V, and the interrupting capacity reaches 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V — numbers that tell you this breaker can handle high-fault-current points in a 480Y/277 V or 400 V industrial panel without cascading upstream.
The 80 A rating holds from 40 °C up to 50 °C; above that it derates gradually — 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Maximum power loss is 19.2 W, which matters for enclosure heat rise calculations.
Auxiliary switching and monitoring
That gives you two independent status contacts for remote indication (breaker ON/OFF) and a separate alarm contact that closes only on a trip event — useful for feeding a PLC input or a panel lamp without sharing the same contact pair.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures.
