■ Purpose

　　The XL hanging power and lighting distribution box (hereinafter referred to as the distribution box) is mainly used in industrial and civil buildings for power distribution, lighting distribution, and motor control in power systems with an AC frequency of 50Hz and a rated voltage below 380V. The distribution box provides overload, short-circuit, and leakage protection for the controlled lines and performs normal circuit switching.

■ Product Model Explanation

■ Usage Environment

　　1. The installation site altitude does not exceed 2000m.

　　2. The ambient air temperature does not exceed +40℃ and is not lower than -5℃, and the average temperature within 24h does not exceed +35℃.

　　3. The ambient air relative humidity does not exceed 50% at the highest temperature of +40℃. At lower temperatures, higher relative humidity is allowed (e.g., 90% humidity at +20℃). However, it should be considered that moderate condensation may occur occasionally due to temperature changes.

　　4. No severe vibration and impact, and the installation inclination does not exceed 5°.

　　5. Pollution degree does not exceed level 3 (conductive pollution exists, or dry non-conductive pollution becomes conductive due to condensation).

　　6. No explosion hazard, and no gases or conductive dust in the medium that can corrode metal and damage insulation.

　　7. In places without rain or snow.

■ Structural Features

　　The XL hanging distribution box is an enclosed box structure, suitable for surface mounting and flush mounting. The box body is made of 1.2-2.0mm cold-rolled steel plate or stainless steel plate, bent and welded. According to the agreement: Single-layer door on the front, circuit breakers and other electrical components are installed inside the box, instruments, buttons, and indicator lights are installed on the door; Double-layer door on the front, circuit breakers and other electrical components are installed in the middle door, and the operating handles are exposed outside the middle door.

　　The box body is powder-coated (box color according to agreement), beautiful and generous, with high mechanical strength and strong adsorption. The electrical components inside the box are installed using galvanized rails and galvanized channel plates. The box door is connected to the box body with multi-strand wires, and the box body is welded to the grounding seat to form a complete grounding protection circuit.

　　The XL hanging distribution box is a new patented product independently developed by our company according to user needs. It has the following structural features: The mounting beam is hung on the door frame, and is combined with the box body and door for easy and quick installation and simple maintenance. The distribution box features a novel structure, compact arrangement, beautiful appearance, and reliable safety.
