The combined terminal design at top and bottom accepts both busbar and conductor termination without swapping parts. Terminal tightening torque is 3.5 Nm for copper conductors rated 60/75 °C — use a torque screwdriver to avoid terminal damage or loose connections. IP20 with connected conductors, IP40 in the handle area — that's standard for a panel-mounted breaker; no special sealing needed for a dry indoor cabinet. ## Environmental tolerance and compliance That covers unheated warehouses and hot enclosures near machinery alike. Halogen-free and silicon-free construction — important for environments where outgassing from a short-circuit event could contaminate nearby contacts or optics.","metaTitle":"Siemens 5SJ4220-8HG41 2-Pole MCB, D-Curve, 10 kA","metaDescription":"Siemens SENTRON 5SJ4220-8HG41 2-pole miniature circuit breaker, D tripping characteristic, 10 kA per EN 60898.
