1. Explosion-proof type is increased safety and explosion-proof composite structure;

2. The shell is molded with high-strength glass fiber unsaturated polyester resin, which has the characteristics of corrosion resistance, impact resistance and thermal stability.

3. When the rated current is 16A, the number of cores is divided into 3 cores, 4 cores and 5 cores. When the rated current is 32A, the number of cores is 4 cores and 5 cores. Users can choose according to their needs;

4. Has a reliable interlock function, that is, after the plug is inserted into the base body, the plug should be rotated so that the arrow on the plug is aligned with the “I” meter, and the plug cannot be pulled out; only the rotary plug aligns the arrow on the plug. O" table is cut off, then the plug can be pulled out;

5. The plug has reliable contact performance and long service life. The socket in the socket has a flexible louver spring sleeve (made of beryllium bronze and heat treated) to make the plug have self-cleaning characteristics to ensure small contact resistance and The low temperature rises, and the required insertion force is also minimized. The design of the louver spring sleeve ensures the normal function of the plug and socket and the permanent self- cleaning effect, which solves the influence of the plug on the surrounding environment during use (such as Humidity and dust) ensure the electrical transmission performance of the plug;

6. The switch handle is equipped with a padlock, which can be locked when not in use. At this time, the switch cannot be opened;

7. All exposed fasteners of the product are made of stainless steel;

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.
