What is the internal structure of the stainless steel distribution box?

Stainless steel distribution box is a common power distribution equipment widely used in industrial, commercial and civilian fields. Its internal structural design needs to meet electrical safety, heat dissipation, dust prevention and maintenance requirements. The following is a detailed description of its typical internal structure and main components:

1. Box shell

Material: Made of 304 or 316 stainless steel, with anti-corrosion, rust proof, and high temperature resistance characteristics, suitable for humid or corrosive environments.

Protection level: usually IP54/IP65, achieved through sealing strips, waterproof locks, and ventilation hole dust nets to prevent dust and water.

2. Internal framework and installation components

Customized bracket: Some boxes are equipped with multi-layer guide rails or adjustable brackets to adapt to different specifications of equipment.

Backboard: Galvanized steel plate or insulation board, providing structural support and electrical isolation, with surface openings for easy wiring.

3. Core electrical components

Electrical components: including circuit breakers, switches, fuses, relays, etc., used for controlling and protecting circuits.

Terminal block: Large section terminal block for connecting main cables.

4. Cable management

Bottom/top opening: standard knock off hole, equipped with rubber sheath to protect the cable.

Waterproof connector: used for outdoor enclosures to achieve cable sealing.

Cable trunking: Vertical/horizontal cable trunking, distinguishing between strong and weak electrical wiring.
