Product Description

FLRN****2D/*****0 Model indoor AC high-voltage load break switch and fuse combined apparatus contains basic components: double gaps, three operating-positions (breaking, making and earthing) and rotary contact. It adopts SF6 gas for arc-extinguishing and insulating. The moving and fixed contact and earthing contact are installed in the casting epoxy resin enclosure. The enclosure is filled with SF6 gas under 0.**5MPa of pressure. The sealed switch enclosure can be tested by leak localize. The fuse rack is fixed under the load break switch by one end and on the switch cubicle by the other; the impinger part is connected with load break switch forming a reliable trip-driving mechanism. The switch can be mounted either vertically and horizontal. In the switchgear, it is typically installed horizontally by putting a board between cable compartment and busbar compartment. This separate busbar with cable connector as to achieve secure operation and convenient maintenance. When it sparks, the weak point of enclosure on the back will be smashed open, and the pressure release valve open to release the air-flow. Load break switch and earthing switch interlock reliably.
