7. Perform overload and short circuit protection on the controlled circuit and use it as lighting (power) switch for each branch line or as a load step-down start and control motor start, stop, forward and reverse.
1. The outer casing is made of glass fiber reinforced unsaturated polyester resin, which has beautiful appearance, antistatic, anti-photoaging, corrosion resistance, impact resistance and thermal stability.
2. The patented technology of the combined explosion-proof distribution box independently researched and developed, modularized optimization design and combination of the distribution box, make the whole distribution box structure more compact and better use effect; can be arbitrarily combined with each circuit according to requirements The earth has the configuration requirements for power distribution equipment in different places.
3. The industry's first and most recently developed large-scale flameproof single-circuit breaker module (250A, 100A, 63A Ex components) can meet the various specifications of the increased safety enclosure distribution box.
4. All-plastic increased safety type explosion-proof structure, built-in explosion-proof circuit breaker, explosion-proof AC contactor, explosion- proof thermal relay, explosion-proof isolation switch, explosion-proof control button, explosion-proof indicator and other components. The assembled structure between the cabinets can be freely selected.
5. There is a special operating mechanism on the cover plate to achieve full-close operation. Padlocks can be added according to requirements to avoid misuse.
6. The main switch and sub-switch operation panels are clearly distinguishable for easy on-site identification.
7. All exposed fasteners are made of stainless steel.
8. Cable in and out of the line, according to user requirements can be made up and down, down and down, up and down, down and up and other forms.
9. The inlet and outlet ports are usually made of pipe threads, and the cable clamping and sealing device is arranged. It can also be made into metric thread, NPT thread, etc. according to the requirements of the user's site.
