EJX-S series explosion-proof and anti-corrosion junction box

EJX-S series explosion-proof and anti-corrosion junction box The casing of portable instruments is sometimes made of plastic or metal. When selecting a plastic casing, in order to ensure that the plastic casing does not accumulate dangerous static electricity during normal operation, its surface resistance should not exceed 1 × 109 Ω. The plastic casing should undergo impact resistance and thermal stability tests.

Electrical equipment that generates sparks, arcs, or hazardous temperatures during normal operation, as well as Class I electrical equipment with a power greater than 250W or a current greater than 5A, must be electrically connected to the equipment body using a junction box. A junction box is a component that connects cables or wires to electrical equipment. Explosion proof wiring is widely used in Class I explosion-proof electrical equipment.
