FLN36-40.5D/T630 indoor sulfur hexafluoride (SF6) load switch and FLN36-40.5DR/125 load switch fuse combination are suitable for power stations and industrial electrical equipment with three-phase AC 50/60Hz ring network or terminal power supply. They are used as load control line protection for power systems. The load switch divides and closes load current, closed-loop current, no-load transformer and cable charging current; Combination electrical appliances can break any current under rated short-circuit current and are suitable for electrical complete sets of equipment such as ring main units and box type substations.
