model implication



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 industry's first and most recently developed large-scale (current) flameproof single-circuit breaker module (250a, 100a, 63a ex components) can meet the use of increased safety enclosure explosion-proof circuit breakers.

3. built-in explosion-proof circuit breaker module. fully enclosed operation is realized by a special operating mechanism on the cover plate, and a padlock can be added according to requirements to avoid misoperation.

4. the box and cover are labyrinth structure, which is formed by double-component sealing styrofoam line casting, which has good protection performance.

5. all exposed fasteners are made of stainless steel.

6. 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.

7. steel pipes and cable wiring are available.

main technical parameters


order note

1. according to the model implication's rules to select regularly, and ex-mark should be added behind model implication;

2. if there are some special requirements, it should be pointed as ordering.
