Detailed

FZN25A-12（D）/T630-20 FZRN25A-12（D）/T200-31.5 AC high voltage gas production load switch/High voltage load switch-fuse combination from JUCRO Electric

FZN25A-12(D)/T630 indoor AC high voltage vacuum load switch (hereinafter referred to as load switch) is suitable for three-phase AC, 50Hz, 12KV power supply network, as the breaking load current and closing short-circuit current. The product is equipped with manual and motor operating mechanism, especially suitable for occasions under severe conditions, without long maintenance period and frequent operation requirements. Vacuum load switch with fuses - fuse combination appliances (hereinafter referred to as combination appliances). FZN25A-12(D)/T200 can break short-circuit current for short-circuit protection. The product has a mechanism tripping, and the fuse has a bumper. When an overload current or a short-circuit current is passed, the fuse is blown, and the striker hits the trip device to automatically open the load switch to avoid phase loss operation.

Normal use environment:

1. Ambient air temperature: up to +40 ° C, minimum -25 ° C;

2. The altitude does not exceed 1000mm;

3. The daily average relative humidity is not more than 95%, and the monthly average is not more than 90%;

4. Earthquake intensity: below level 8;

5. The surrounding air should be free from harmful gases such as corrosive or flammable gases and water vapor.
