Product Model

Model and Specification of Explosion-Proof Distribution Box

Explosion-proof lighting distribution boxes and cabinets come in a variety of models. They vary in terms of materials, including metal and flame-retardant plastic; installation methods, such as vertical, hanging, concealed, or exposed installations; and voltage levels, including 380V and 220V.

1. GCK, GCS, and MNS are low-voltage withdrawable switchgear cabinets.

2. GGD, GDH, and PGL are low-voltage fixed switchgear cabinets.

3. XZW is a comprehensive distribution box.

4. ZBW is a box-type substation.

5. XL and GXL are low-voltage distribution cabinets and construction site boxes; XF for electrical control.

6. PZ20 and PZ30 series are terminal lighting distribution boxes.

7. PZ40 and XDD(R) are electric metering boxes.

8. PXT(R)K-□/□-□/□-□/□-IP□ series specifications are interpreted as follows:

1. PXT for surface-mounted distribution boxes, (R) for concealed installation.

2. K indicates a series of wiring methods.

3. □/□ for rated current/short-time withstand current: e.g., 250/10 indicates a rated current of 250A and a short-time withstand current of 10kA, which can be reduced as per customer requirements.

4. □/□ for inlet style: □/1 for single-phase input; □/3 for three-phase input; 1/3 for mixed input.

5. □ for outlet circuits: single-phase circuits; three-phase circuits, e.g., 3 single-phase 6 circuits, three-phase 3 circuits.

6. □/□ for main switch type/protection level; e.g., 1/IP30 for single-phase main switch/IP30 protection; 3/IP30 for three-phase main switch/IP30 protection.

9. Electrical schematic numbers:

1. JL for metering box PXT01 series;

2. CZ for socket box PXT02 series;

3. ZM for lighting box PXT03 series;

4. DL for power box PXT04 series;

5. JC for metering and socket box PXT05 series;

6. JZ for metering and lighting box PXT06 series;

7. JD for metering and power box PXT07 series;

8. ZC for lighting and socket box PXT08 series;

9. DC for power and socket box PXT09 series;

10. DZ for power and lighting box PXT10 series;

11. HH for hybrid function box PXT11 series;

12. ZN for intelligent box PXT12 series.

10. Electrical cabinet naming codes:

AH for high-voltage switchgear;

AM for high-voltage metering cabinet;

AA for high-voltage distribution cabinet;

AJ for high-voltage capacitor cabinet;

AP for low-voltage power distribution cabinet;

AL for low-voltage lighting distribution cabinet;

APE for emergency power distribution cabinet;

ALE for emergency lighting distribution cabinet;

AF for low-voltage load switch cabinet;

ACC or ACP for low-voltage capacitor compensation cabinet;

AD for direct current distribution cabinet;

AS for operation signal cabinet;

AC for control panel cabinet;

AR for relay protection cabinet;

AW for metering cabinet;

AE for excitation cabinet;

ARC for low-voltage leakage circuit breaker cabinet;

AT for dual power source automatic transfer cabinet;

AM for multi-source power distribution cabinet;

AK for knife switch cabinet;

AX for power socket cabinet;

ABC for building automation controller cabinet;

AFC for fire alarm control cabinet;

ABC for equipment monitor cabinet;

ADD for residential wiring cabinet;

ATF for signal amplifier cabinet;

AVP for distributor cabinet; AXT for terminal junction box.

Example of GCK:

The first ‘G’ denotes a distribution cabinet;

The second ‘C’ signifies drawer-type;

The third ‘K’ represents control.


The first ‘G’ denotes a distribution cabinet;

The second ‘G’ stands for fixed type;

The third ‘D’ represents power distribution box. Other examples like 1AP2, 2AP1, 3APc, 7AP, 1KX, etc., are common codes used in engineering distribution systems. These are arranged by designers and aren’t strictly standardized.

However, they follow certain patterns, e.g., AL for distribution boxes, AP for power distribution boxes, KX for control boxes, etc. For instance, 1AL1b indicates a Type B distribution box at Position 1 on the first floor; AT-DT denotes an elevator distribution box; 1AP2 refers to the second position power distribution box on the first floor.
