Width is 36 mm (2 width units), depth 76 mm, installation depth 70 mm — fits the same footprint as any 2-pole 5SL-series breaker. Mounting position any, so horizontal or vertical busbar feeds work without derating the thermal trip. Tightening torque is 2.5 to 3 N·m — a standard screwdriver setting, no special tool needed. The housing is IP20 with conductors connected, which is the usual protection level for enclosed distribution boards.
