Product Description

The shell of the explosion-proof control box is made of aluminum alloy, and the surface is high-voltage electrostatic spray with beautiful appearance. The product protection grade is IP65. It is mainly suitable for IIA, IIB, IIC explosive gas environments. The main ammeter, switch, button, indicator light, thermal relay and other components in the box can be freely combined to achieve various functions.
Explosion-proof junction box is a special power distribution equipment used in various high-risk places. Compared with civilian junction boxes, it is a power distribution box with explosion-proof function that has been transformed from various explosion-proof.
Explosion-proof and anti-corrosion junction boxes are classified into: according to the functional material form: intrinsically safe explosion-proof junction box, aluminum alloy explosion-proof junction box, stainless steel explosion-proof junction box, steel explosion-proof junction box; according to the use structure, it is divided into: wall-mounted explosion-proof junction box And vertical explosion-proof junction box. Explosion-proof junction box series: The shell is made of impact-resistant glass fiber reinforced polyester material, and all metal parts are. The joint surface of the cover and the base is designed in a concave and convex shape, with a silicone rubber sealing structure to ensure the IP65 protection level. It is used as the branching and wiring for connecting various electrical equipment and instruments in the voltage 220V/380V line.
The junction box has three specifications: the built-in screw self-locking terminal has a specification of 2.5-3.5 square millimeters, and the lead wire is fixedly connected. Different types and specifications of cable glands meet different cable introductions: The plastic cable gland inlet (installation end) is metric thread, with anti-loosening clamping jaws inside, which has good mechanical characteristics. Unused cable entries can be sealed with blanking plugs for future retrofits and expansions for more convenient installations.
