Ip65 enclosure distribution box High-end waterproof distribution box.Suitable for waterproof and dustproof lamps in special occasions.waterproof, moisture-proof, strong, flame retardant, good insulation and heat dissipation, large space.Ip65 waterproof and dustproof design · Simple appearance.Waterproof grade IP65· Safe waterproof, not all distribution boxes are the same as ours. flame retardant raw materials can not open fire high quality PC safety flame retardant.
Ip65 enclosure distribution box flame retardant raw materials can not open fire high quality PC safety flame retardant. The material is firm and easy to install.Flip window, more intuitive, better sealing performance.
The shell of the waterproof Ip65 Enclosure Distribution Box is made of high-quality cold-rolled steel plate, which is pressed by a mold. The home improvement rain cap (a structure similar to a hat specially developed for rain protection) has a very beautiful appearance, anti-static, corrosion-resistant and durable. The color of the waterproof distribution box can be made in any color according to the customer's needs. It adopts high-voltage electrostatic spray treatment, and the anti-corrosion grade is F1. The protection level is also very high. All exposed fasteners are made of stainless steel, and seals are made of silicone rubber. This product is mainly used in circuits with AC 50Hz, voltage to 380V and below, DC to 440 and below, and current within 100A, as a lighting control at the work site , Power transmission, power control and other functions. Built-in C65 high breaking miniature circuit breaker. It can be equipped with functions such as leakage protection, photoelectric control, etc. The electrical original manufacturer can also make it according to the needs of customers.
1. The working voltage, current, frequency and grade of the selected electrical components must meet their working requirements, and the installation and wiring should be neat and reliable.
Two, the distribution box of each branch line or protection needs selective place, generally should be equipped with protective appliances.
Was elected with fuses or automatic switch protection appliance, the melt rated current of the fuse or automatic switch overcurrent tripping speed of the rated current, should as far as possible close to but not less than the load calculation of protected line current, and shall ensure that in the event of a normal short-time overload (such as motor starting, etc.), protection from protected circuit disconnection.
1. When choosing fuse to protect the distribution line, the fuse should be installed on each pole of each phase without grounding (zero). When the fuse is used for short-circuit protection, the selection of the cross section of the melt or conductor shall comply with the following provisions:
1) The rated current of the melt shall not be more than 2.5 times the allowable current carrying capacity of the cable or the insulated wire through the pipe or 1.5 times the allowable current carrying capacity of the laid insulated wire.
2) When single-phase short-circuit occurs at the end of the protected line (refers to the neutral point directly grounded to the grid), the short-circuit current shall not be less than 4 times of the rated current of the fuse.
