It is configured for line protection — no phase-failure detection, no communication module, no auxiliary contacts.
The interrupting ratings span the common industrial voltages: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. The 690 V figure (17 kA) is the one to check if the breaker lands in a 690 V mining or marine distribution board.
Current derating across temperature
Rated continuous current holds at 160 A from 40 °C through 50 °C, then begins a gradual derating: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. If the panel ambient runs at 55 °C or above, the effective ampacity drops — account for that when sizing the load cable and the upstream feeder.
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration.
