Product description

Fully Sealed And Fully Insulated
All live parts and switches of SFR6-12/24 are sealed in the SF6 air box, which is welded with 3 mm thick stainless steel plate, and there is a reliable pressure relief channel at the bottom of the cabinet, which can protect the operator to the greatest extent
The insulated bus bar is used to connect the gas box and the gas box, which is safe and convenient, and the insulated bus bar and the gas box are isolated from each other, which can effectively prevent the spread of accidents in case of failure.

Use Environment
SFR6-12/24 is suitable for use in various environments such as high and low temperature (+40℃～-40℃), humidity, dust, pollution, mines, high altitude (2000 meters), and short-term immersion within 24 hours will not affect
Note: If the altitude is higher, please indicate the specific altitude.

Modular Design
SFR6-12/24 adopts a modular design scheme, and its basic module units are load switch modules, combined electrical module units and other special function modules.

Fully Sealed And Fully Insulated
All SFR6-12/24 modules can realize side expansion or top appearance and top expansion connection according to user requirements, which can meet the needs of power supply solutions to the greatest extent.

The Product Meets The Standard
International Standard IEC600056 IEC60298 IEC60129 IEC60420 IEC60265 IEC60694
Chinese Standard GB3804 GB3906 GB11022
