Product details

Above that temperature, derate per the IEC 60947-2 thermal curve. Category A utilisation means it is not intended for current-limiting duty — the let-through energy is higher than a current-limiting breaker, so verify the downstream equipment's I²t withstand.

Mounts on a backplate in horizontal or vertical orientation. The 108 mm width, 137 mm height, and 80 mm depth fit standard enclosure cutouts. Front connection top and bottom simplifies busbar or cable routing. Everlink terminals accept 2.5…95 mm² rigid or stranded aluminium/copper, or 2.5…70 mm² flexible copper — no lug adaptors needed for the common wire sizes. IK07 impact resistance handles incidental tool contact during panel work.
