Product Description


FLN36-12D series high voltage AC indoor load switch is applied in the three-phase, AC50Hz, rated voltage up to12KV, rated current 630A  electric-supplying network. Mainly applied in three-phase RMU net pr ending electric-supply city distribution station and industrial electrical equipments, with load-control and short-circuit protection.

The load switch integrates breaking, closing earthing as a  multifunction switching device, in a whole sealed, epoxide-resin reinforced structure housing with filling 0.05MPa SF6 gas inside. 
It's the main switching component for RMU switchgear. Reliable, free-maintain.
Can run safely over 20 years in normal.


Altitude: below 3000m
Air temperature maximum is +40ºC, minimum is -30ºC.
Relative temperature: diary average ≤95%, monthly average ≤90%
No frequent shrink shock.


1.SF6 gas for arc blow-out, no explosive danger, no need to inspect
2. Load switch adopts double fractures, rotatablel moving contacts structure. 3 running situations: breaking, closing, grounding.
3. Component parts all adopt stainless steel material, bottom bracket adopts stainless steel material or carbon steel material of hot-galvanized with UV protection coating  To ensure device normally run in outdoor environment.
4. Strong breaking capacity, safety, reliable, long electrical life, frequent operation.
5. Small volume, light weight, free-maintain,  safe & convenient for operation
