1. explosion-proof type is a combination of increased safety and explosion-proof structure.
2. the outer shell is molded with glass fiber high-strength unsaturated polyester resin (smc), which has the properties of corrosion resistance, impact resistance and thermal stability.
3. when the rated current is 63a, the number of cores is divided into 4 cores and 5 cores. when the rated current is 125a, the number of poles is 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. the o" watch is cut off and 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. the switch cannot be turned on at this time.
7. all exposed fasteners are made of stainless steel.
