Electrical distribution box wh

The WH series electrical distribution box is a versatile, waterproof, and durable enclosure designed for safe power distribution in residential, commercial, and industrial applications.

Overview

A W

H electrical distribution box is a protective enclosure used to house circuit breakers, fuses, and other electrical components for distributing power safely. These boxes are typically made from polycarbonate/ABS or PC-ABS alloy plastics, offering high impact resistance, flame retardancy, and durability under extreme temperatures ranging from -25 °C to +100 °C. Many models, such as the WHA series, are IP65 rated, making them suitable for both indoor and sheltered outdoor installations.

Key FeaturesDIN Rail Mounting: Pre-installed DIN rails allow easy installation of breakers and other modular devices. Waterproof and Dustproof: IP65 protection ensures resistance to water jets and dust ingress, ideal for outdoor or industrial environments. Impact Resistance: IK10 rating provides strong protection against mechanical impacts.

Temperature Range: Operates reliably from -25 °C to +100 °C, suitable for harsh conditions. Versatile Applications: Can be used for lighting circuits, photovoltaic (PV) systems, electric vehicle charging stations, control circuits, and general power distribution. Transparent or Smoked Doors: Some models feature a PC viewing door for quick inspection of breakers without opening the box.

Installation and Use

Mounting: Mark fixing points, drill, and wall-mount the base ensuring it is level. Cable Entry: Open knock-outs and fit appropriately sized cable glands or bushings to maintain sealing. Component Installation: Clip protective devices onto the DIN rail and add neutral/earth bars if required.

Wiring: Dress conductors, maintain bend radius, label circuits, and tighten terminals. Final Check: Close the door, verify gasket compression, and test continuity/insulation. Variants and SizesWH series boxes come in 4 to 26 ways, accommodating different numbers of circuits depending on the application.

Smaller models like the YWBL-WH are compact, lightweight, and suitable for indoor or outdoor solar and EV charging setups, with dimensions around 8. 66 x 8. 27 x 4.

72 inches.

Advantages

Durable and long-lasting: Resistant to aging, high temperatures, and mechanical stress. Flexible and modular: Can be repeatedly disassembled and reconfigured for maintenance or upgrades. Professional-grade safety: Meets Class II insulation standards and provides reliable protection for electrical installations.

In summary, the WH electrical distribution box is a robust, waterproof, and versatile solution for safely distributing electricity in a wide range of environments, from homes and workshops to industrial and renewable energy applications.
