High-voltage switch: fitting consist of load switch and combination electric mainly by the box implement, isolating switch (the current limit of combination fuses in isolating switch), vacuum switch tube, grounding switch, spring operation mechanism etc.High-voltage switch is a kind of function between high voltage circuit breaker and high pressure isolating switch between the electrical appliances, high-voltage switch fuse series and the high pressure often used together; Used to control power transber. High-voltage switch is of simple arcing device, it can be to break a certain load current and load current. But it can't disconnect short-circuit current, so it is general and high pressure fuse series use, with the fuse to short circuit protection.Load switch type: name specificationsFN3系列 FN3-12/400 FN3-12R/400 FN3-12RD/400FN5系列FN5-12/400 FN5-12R/400 FN5-12D/400 FN5-12RD/400 FN5-12RL/400 FN5-12DRL/400FN7系列 FN7-12/400 FN7-12R/400 FN7-12D/400 FN7-12RD/400 FN7-12RA/400 FN7-12DXLRA/400 FN7-12DXLRAF/400FKN12系列FKN12-12/630-20 FKN12-12R/630-20 FKN12-12D/630-20 FKN12-12RD/125-31.5FZN25系列FZN25-12/630-20 FZN25-12R/630-20 FZN25-12D/630-20 FZN25-12RD/125-31.5FZN16系列FZN16-12/630-20 FZN16-12R/630-20 FZN16-12D/630-20 FZN16-12RD/125-31.5FZN21系列FZN21-12/630-20 FZN21-12R/630-20 FZN21-12D/630-20 FZN21-12RD/125-31.5聯(lián)系人：李經(jīng)理
