Product Overview: JXF type low-voltage control distribution box below 630A is suitable for power plants and industrial and enterprises. It is used for three-phase three wire, three-phase four wire, and three-phase five wire systems with AC voltage of 500V and below, for power and lighting distribution. JXF type power distribution cabinet is an indoor device, installed against the wall and maintained in front of the screen.
Model and meaning:
Normal usage conditions:
Environmental temperature: -50 ℃ to+40 ℃, and the average temperature within 24 hours does not exceed+36 ℃.
Altitude: not exceeding 2500m
Relative humidity: not exceeding 50% when the ambient air temperature is+40 ℃.
At lower temperatures, there can be higher relative humidity (such as 90% at+20 ℃). Considering temperature changes, moderate condensation can be generated. When installing equipment, the inclination from the vertical plane should not exceed 5 ℃. The equipment should be installed in a place without severe vibration, impact, and corrosion.
Note: If the above conditions cannot be met and the user has special requirements, they can negotiate with our company to resolve them.
Product structure: Low voltage control distribution box indoor wall mounted, single-sided front opening power distribution device. Its basic structure is made by bending steel plates and welding angle steel. A knife switch operating handle can be installed on the front right side for power cut-off and connection operations. Operation buttons, indicator lights, and display instruments can be installed on the box door. After opening the box, all internal equipment of the distribution box is exposed for easy maintenance and repair. This distribution box is equipped with air circuit breakers, fuses as short-circuit protection, as well as contactors and thermal relays. Both the door and the shell are welded with grounding screws to ensure reliable connection between the shell and the ground.
