Line protection MCCB with 160 A continuous rating and high interrupting capacity
The interrupting capacity hits 121 kA at 240 V AC and 75.6 kA at 415 V AC, which means it clears high-fault conditions on the secondary side of a large transformer or at a service entrance without cascading upstream breakers.
Rated breaking capacity is specified at five voltage points: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The 415 V figure is the one to watch for European 400 V networks — 75.6 kA covers most industrial transformer ratings up to 2 MVA.
Integrated auxiliary switches and shunt trip
That saves panel space and wiring time compared to adding them as field-installed accessories. The auxiliary switches report breaker position to a PLC or status lamp; the shunt trip lets an emergency-stop circuit or fire-alarm relay kill power without a separate contactor.
Rated current holds at 160 A from 40 °C through 50 °C, then steps down: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Maximum power dissipation is 38 W — relevant for enclosure heat calculations when grouping several breakers in a sealed panel.
