It carries a rated current of 80 A at 40 °C, with breaking capacities that step down from 52.5 kA at 240 VAC to 7.5 kA at 690 VAC — so the same frame can be applied across different supply voltages without swapping hardware, as long as the fault level at the point of installation stays under the curve.
The breaker is rated 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. Thermal derating is shallow: it holds 80 A from 40 °C up to 50 °C, then drops to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C — so in a warm panel the full 80 A is usable up to 50 °C, and you lose less than 10 % even at 70 °C.
Integrated undervoltage release and auxiliary switches
The two auxiliary switches provide independent status feedback (open/closed) to a PLC or indication lamp without extra wiring terminals. No communication module is included; this is a hardwired breaker.
Mounting is screw-clamp to the panel backplate, not DIN-rail snap-on.
