It carries a continuous current rating of 50 A at 40 °C, derating to 45 A at 70 °C — per the datasheet, the thermal curve holds flat to 50 °C then drops one amp per 5 °C step. Breaking capacity is the headline spec here: 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V. The 415 V and 440 V ratings (154 kA and 121 kA) still cover most European and Asian industrial distribution levels with headroom.
Integrated accessories and wiring note
The two HQ auxiliary switches provide position feedback (open/closed) to a DCS or status lamp. No undervoltage release is fitted on this order code, so if you need UVR for undervoltage protection on a motor feeder, this is not the variant. Dimensions: 130 mm height, 76.2 mm width (3 inches — standard MCCB footprint for panel busbar spacing), 70 mm depth. The 3-pole block occupies three 18 mm pole positions on a DIN rail or direct-mount plate.
The shunt trip coil and auxiliary switches are rated for the same ambient envelope, but verify the shunt trip control voltage matches your panel's auxiliary supply — the evidence does not list the coil voltage on this order code.
