Product details

The interrupting capacity hits 440 kA at 240 V and 330 kA at 415 V and 440 V, dropping to 220 kA at 500 V and 52.5 kA at 690 V. That kind of headroom means it clears high-fault scenarios without cascading upstream — selectivity stays intact even on a stiff utility feed. Front-side IP40 keeps dust out of the mechanism in a clean panel environment; the enclosure is sized at 105 mm wide, 86 mm deep, 181 mm tall — standard 3-pole MCCB footprint for DIN-rail or screw-mount integration.

Integration and mounting notes

Mounts on DIN rail or via the screw-mount lugs that come with the frame. The front IP40 rating means it can go in a ventilated enclosure without a separate cover over the breaker face. Optional motor drive is available for remote tripping or re-closing schemes.

Frequently asked questions

What is the interrupting capacity of this MCCB at 240 V?

440 kA at 240 V, dropping to 330 kA at 415 V, 220 kA at 500 V, and 52.5 kA at 690 V. This gives generous selectivity headroom for most industrial service-entrance or feeder applications.
