Outdoor Waterproof Small Distribution Box

Shangming is a reliable manufacturer and supplier of Outdoor Waterproof Small Distribution Boxes. This product prevents dust from entering and is resistant to outdoor weather changes. Made of stainless steel, it is not easily corroded and is suitable for AC 220V/380V low-voltage systems.

Product Advantages

1. High Protection Rating

Our outdoor waterproof mini distribution box boasts a high protection rating of IP65/IP66, providing complete dustproof protection and resistance to heavy rain, sprays, and even high-pressure water washing. Our factory tests show that after 15 minutes of simulated heavy rain (50L/min, 3m distance), the interior of the box remains completely dry.

The distribution box features a fully sealed design with a food-grade silicone sealing strip in the cover and PG threaded waterproof cable connectors for reliable sealing.

2. High Safety

This mini distribution box is equipped with a 30mA high-sensitivity residual current circuit breaker, interrupting faults within 0.1 seconds to prevent electric shock; all metal parts are reliably grounded with a grounding resistance ≤0.1Ω.

The door panel features a lock with a protective cover, preventing rainwater from seeping into the lock cylinder and preventing unauthorized personnel from operating the switches.

3. Convenient Installation and Maintenance

Our lightweight design and compact size, along with pre-drilled mounting holes on the back, allow for quick wall mounting, enabling installation by a single person.

The front-opening door allows for tool-free opening of the box cover, with a clear component layout and ample wiring space.

The distribution box features a modular DIN rail system, compatible with mainstream MCB/RCBO systems from Chint, Delixi, ABB, and others. Component replacement can be completed within 5 minutes in case of failure.

4. Long Lifespan

Shangming selects high-quality materials; the stainless steel box has a lifespan of ≥15 years. With no moving mechanical parts, regular lubrication is unnecessary, and the sealed structure prevents internal dust accumulation, reducing cleaning requirements.

We use standard low-voltage electrical components, ensuring ample market supply and low replacement costs. Spare parts are also available upon request.

5. Customization Support

This outdoor distribution box can be used for streetlights, surveillance cameras, billboards, water pumps, charging stations, agricultural irrigation, temporary construction sites, etc. Customization is required based on specific requirements. It supports any combination of 2–12 circuits and offers optional colors (gray, white, black), locks, and special wiring terminals.

In-stock products are delivered within 5–7 business days; customized products are delivered within 15–25 business days depending on urgency and order quantity.

Selection Guide

When selecting an outdoor waterproof mini distribution box, a comprehensive evaluation should be conducted considering the usage environment, electrical configuration, safety level, and installation method. You can directly provide your needs and drawings if available, and Shangming's technical team will provide a more specific and suitable solution as soon as possible.

The basic selection criteria mainly focus on these aspects:

1. Usage Environment and Protection Level

For general outdoor use, IP65 is recommended, providing dust and rain splash protection. For areas with heavy rain, high humidity, or near water sources, IP66 is recommended.

In areas frequently exposed to high temperatures and strong sunlight, UV-resistant materials should be selected to prevent the casing from aging and becoming brittle. Stainless steel should be used in coastal areas and chemical industrial zones.

2. Enclosure Material

Shangming offers a choice of materials including iron, cold-rolled steel plate, 201 stainless steel, 304 stainless steel, and 316 stainless steel. For outdoor use, stainless steel is the preferred choice due to its high strength, impact resistance, and resistance to corrosion.

3. Dimensions and Internal Space

Sufficient installation space needs to be reserved based on the number of circuits and circuit breaker specifications. Note whether DIN rail mounting and terminal blocks are required.

Reserving expansion space is crucial. It is recommended to reserve 20-30% margin based on actual needs for future expansion or maintenance.

4. Electrical Configuration Matching

Please specify the main internal components: MCB/RCCB/RCBO, relays, contactors, surge protection modules, etc.

Confirm rated parameters: voltage level (e.g., AC 220V/380V), current capacity.

Also, confirm whether the enclosure supports multi-circuit distribution or custom openings.

5. Installation Method

Wall-mounted: For small outdoor distribution boxes, wall-mounted installation is recommended, suitable for building exterior walls and equipment sides.

For use in roads, parks, and lighting systems, column mounting can also be considered.

If needed, the enclosure can be equipped with mounting brackets, rear panel mounting holes, and anti-tamper screws.

6. Safety and Compliance Requirements

Does the project require a locking structure?

What standards and certification documents are required? Our products are CE certified and comply with IEC, ANSI, BS, DIN, AS/NZS, and other standards. Please inform us of your requirements before placing an order.

What Are the Daily Maintenance Considerations for Outdoor Waterproof Miniature Distribution Boxes?

Regularly check the box for cracks, deformation, rust, or aging; check the sealing strips for aging or damage, and replace them if necessary.

When inspecting the interior, clean the dust inside the box, especially the guide rails and the surface of the circuit breakers. Check the circuit breakers, terminal blocks, and wiring screws for looseness, and check the wires for overheating discoloration and damage to the insulation.

Also, pay attention to any abnormal noises, odors, or localized temperature rises, and periodically test the reliability of the residual current device (RCD).
