25 A MCCB for distribution panels
The 4-pole version (4P) switches all four poles, with neutral on the left. IP40 front-face protection keeps tools and fingers out; IK07 impact resistance handles accidental panel-door strikes. Mounting is backplate with horizontal or vertical orientation — no DIN-rail clip on this frame, so budget for panel-mount hardware.
Termination and wiring
Front-face connection top and bottom via Everlink lugs. Wire range: 2.5…95 mm² rigid or stranded aluminium/copper; 2.5…70 mm² flexible copper. The 35 mm connection pitch with spreaders (27 mm without) matches standard busbar systems. Strip and torque per the manufacturer's published values — the lug design accepts both Cu and Al conductors without bi-metal washers, but aluminium terminations should be retorqued after thermal cycling.
