Its interrupting capacity reaches 121 kA at 240 V and holds at 75.6 kA through 440 V, dropping to 52.5 kA at 500 V and 3 kA at 690 V — the high short-circuit ratings mean it handles fault currents in low-voltage mains without cascading upstream breakers.
Dimensions are 86 mm deep, 140 mm wide, and 181 mm tall — the 140 mm width is the footprint you need to reserve per pole count; four poles at this frame size fit a typical 600 mm wide panel with room for adjacent breakers or busbars.
The adjustable thermal-magnetic trip range is 95 A minimum to 756 A maximum, so it can be tuned to protect feeders or large branch circuits. Power loss is 5.4 W maximum at rated current, which matters for enclosure heat calculations in sealed panels.
