Good Safety Performance

If internal arcing occurs, the housing has an internal structure weak point, it will be rushed to open, followed by the cabinet above the shutter release arc red open air overpressure stream-oriented outside the cabinet, ensure that the switch cabinet security checks.
High Security and Reliability

Load break switch sets closing, opening, earthing three at one, filled with SF6 gas encapsulated in epoxy resin housing, three-position interlock, have compact structure.
Other Advantages

Small size, light weight, maintenance-free, easy and safe to operate.

Overview
Technical Parameters

FLN36-12D/T630-20 load switch uses SF6 gas as insulation and arc extinguishing medium; has three positions: closing, opening, and grounding; dynamic and static contacts have double-break isolation, higher reliability; extended electrical life (E3 level, rated current 100 times); extended mechanical life (M2 level, 5000 times); rated thermal stability current (4s) 20KA; closing and opening positions are electric or manual operation, and the grounding position is manual operation; the electric operation power supply is available in AC220V, AC110V, DC220V. DC110V, DC48V, DC24V; has electric and manual operation interlocking, and operation power supply polarity reverse connection protection function;
