Interrupting capacity and trip curve for motor and transformer circuits
The 5SJ4220-8HG41 carries a DC rating of 60 V.
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.
