Product features
Increased safety type enclosure with explosion-proof components;
The shell is made of glass fiber reinforced unsaturated polyester resin, which has excellent performance of antistatic, impact resistance, corrosion resistance and thermal stability;
The flameproof control switch has compact structure, good reliability, small volume, strong on-off ability, long service life, and multiple functions for users to choose. The explosion-proof button adopts ultrasonic packaging technology to ensure reliable bonding strength. The function of the button can be combined by unit. The explosion-proof indicator light adopts special design, and the AC 220 V ~ 380 V is universal.
The joint surface of shell and cover adopts curved sealing structure, which has good waterproof and dustproof ability;
The exposed fasteners are designed with stainless steel anti dropping type, which is convenient for maintenance.
