It carries a continuous current rating of 160 A at 40 °C across all three poles, with no derating needed up to 50 °C — at 55 °C it still holds 158 A, and at 70 °C it derates to 150 A. The 3-pole construction suits three-phase feeder or branch circuits in commercial and industrial switchboards. Breaking capacity is rated at 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Integrated auxiliaries and releases
It also includes two auxiliary switches (HQ design) for remote status indication, position feedback to a PLC, or interlocking logic. The trip indicator is not present, so visual trip status must be read from the handle position or via the auxiliary switches.
Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard 3-pole MCCB footprint for DIN-rail or panel-mount installation. The 70 mm depth matters when planning gland-plate clearance or enclosure depth in retrofit panels where existing backpanel wiring is fixed.
