LWXL power distribution box is suitable for AC 50 (60) HZ, voltage up to 690V power supply system, for power or lighting distribution, suitable for industrial and mining enterprises and various civil buildings, with overload, short circuit and leakage protection. This product conforms to GB7251.1 “Low-voltage complete sets of switchgear and control equipment” standard.
The ambient temperature is not higher than +40°C, not lower than -5°C, and the average temperature over a 24-hour period is not higher than +30°C. The relative humidity of the ambient air is not higher than 50 per cent at +40°C. -The relative temperature of the ambient air should not be higher than 50 per cent at +40°C. At lower temperatures a higher relative humidity is possible, but possible condensation due to temperature changes should be taken into account (e.g. 90 per cent at +20C).
90 per cent at +20C, for example).
-The equipment should be installed in a place free from severe vibrations and shocks, and where the electrical components are not subject to corrosion.
-The inclination of the equipment to the ground should not exceed 5 degrees.
-Users can consult with the manufacturer for special requirements.
The box body is made of high-quality steel plate bent and welded, with electrostatic spraying surface treatment, floor-mounted installation. The door of the box is generally a single door, which can also be divided into upper and lower doors, in order to improve the protection level when the door is opened, the two-layer door can be added, so that the operating part of the components is exposed to the two-layer door, which will greatly improve the personal safety of the operators.
Outdoor protection type power distribution box is equipped with rainproof canopy on the top, and the door and box body adopt U-type double-folded edges with embedded rubber strips, and the protection level reaches IP54.
