MCB for 1 A lighting and control circuits
It breaks fault currents up to 4.5 kA per EN 60898 and IEC 60947-2, which means it clears a hard short on a 1 A lighting or control circuit without welding its contacts — the energy limiting class 3 rating confirms it restricts let-through energy to protect downstream wiring. The C-curve (5-10x In) handles moderate inrush from contactor coils or small transformers without nuisance tripping, while still protecting the 1 A branch.
DIN-rail fit and wire termination
The screw terminals accept solid or stranded copper from 0.75 mm² up to 25 mm², with a recommended tightening torque of 2.5 to 3 N·m. Mounting position is unrestricted, and the housing is IP20 rated with connected conductors, so it belongs inside a panel, not exposed to washdown.
