Product details

At 415 V AC this breaker clears 36 kA Icu; at 480 V AC (UL 60947-4-1) it holds 35 kA, and at 600 V AC it still manages 15 kA. That puts it in the F class for 415 V systems — enough headroom for most industrial distribution panels downstream of a transformer.

Mounts flat on a backplate in horizontal or vertical orientation. Front connection on both line and load sides simplifies busbar or cable routing in a panel. The 105 mm width and 161 mm height fit standard enclosure cutouts for the NSX250F frame. IP40 front face and IK07 impact resistance are adequate for enclosed distribution boards.
