How to choose explosion-proof junction box
Date:2022-05-29 16:34:58 Views:579
The selection of explosion-proof junction box is mainly based on three conditions:
1. Explosion-proof level;
2. Sensor supply voltage;
3. The number of connected sensors (four-wire, six-wire, eight-wire, ten-wire, etc.).
There are various models of explosion-proof junction boxes. Although different models have the same basic functions, there will be certain differences in the parameters between them. The following models are the more common models:
1. The general models are BJX-10A, BJX-20A/12, BXK8050, BXM(D) series explosion-proof junction boxes, taking the BJX-20/30 model as an example: the number of terminals is 20, the rated current is 30A, and the upper The thread of the wire and the wire inlet is 1*G20, 1, and the wire exits from the bottom, and the thread of the outlet is 2*G15, 4. 50 units can be wall-mounted and floor-standing.
2. According to the size, the models of explosion-proof junction boxes are 135X135X110mm, 200X135X110mm, 300X200X120mm, 400X300X150mm, etc.
Consumers should choose the appropriate explosion-proof junction box model and size according to the explosion-proof requirements and wiring requirements, etc., to improve the explosion-proof function and enhance the safety of use.
Scope of application of explosion-proof and anti-corrosion junction box
Zone 1.1 and Zone 2 hazardous locations.
2. A, B, IIC explosive gas environment.
3. Temperature group: T1-T6;
4. Used in chemical, oil refining, oil exploration, offshore oil platforms, tankers, and other dangerous places;
