Metal waterproof socket box: industrial protection, as solid as a rock


Born to cope with the most demanding industrial environments, our metal waterproof socket box integrates sturdy protection, excellent sealing, and flexible power configuration, serving as a reliable cornerstone for ensuring continuous power supply and safe operation of equipment.

Core advantages:

Military grade protection, fearless of challenges: using high-strength galvanized steel plate/aluminum alloy shell, the structure is sturdy, impact resistant, and corrosion-resistant. The protection level is up to IP65/IP66/IP67, completely dust-proof, and can withstand high-pressure water column flushing or short-term immersion. It can easily cope with complex environments such as outdoor, construction sites, factories, docks, etc. that are humid, dusty, oily, and prone to collision.

Craftsmanship in sealing, no dripping: High quality silicone sealing rings are used between the box body and the box cover, combined with multi-point locking or bolt fastening design, to achieve comprehensive compression sealing. The inlet and outlet are equipped with waterproof gland heads as standard, forming a complete sealing and protection system.

Modular configuration, flexible definition of power core: Equipped with high-quality rails internally, it can flexibly install industrial socket modules (such as IP44/IP67 sockets), circuit breakers, lightning arresters, contactors, etc., meeting the multifunctional integration requirements from conventional power supply to equipment control and signal transmission. It is your exclusive compact distribution center.

Detail highlights professionalism:

The surface is coated with environmentally friendly electrostatic spraying, which is corrosion-resistant, wear-resistant, and easy to clean.

Transparent window design (optional), making the running status clear at a glance.

Support silk screen printing or customized labeling (optional waterproof PVC/metal nameplate) for easy equipment identification and management.

Customization process for socket boxes

Internal structure

Step 1: Define Core Electrical Specifications

Socket Selection Criteria:

  • Ingress Protection: IP44 (splash-proof for sheltered areas) or IP67 (fully waterproof for harsh outdoor/industrial use).

  • Current Rating: 16A, 32A, 63A, or 125A (dictates maximum load capacity).

  • Pole Configuration:

    • 2-pole (Live + Neutral)

    • 3-pole (L+N+Earth, most common)

    • 4-pole (3-phase + Earth)

    • 5-pole (3-phase + Neutral + Earth)

  • Type: Industrial connector (e.g., IEC 60309 standard), typically matched to the required IP rating and current.

Panel Layout:


Define the quantity and combination of sockets for the enclosure (e.g., two 32A IP67 3-pole sockets + one 16A IP44 3-pole socket).

Step 2: Choose Protection & Control Devices

Circuit Breaker Selection:

  • Brand Examples: CHINT, Schneider, DELIXI, ABB, Siemens.

  • Poles: Match the number of poles to the socket configuration.

  • Type:

    • RCBO: Combines overload, short-circuit, and earth leakage protection (typically 30mA for personal safety).

    • MCB: Provides overload and short-circuit protection only.

  • Rated Current: Should correspond to the connected socket rating (e.g., 32A for a 32A socket).

Step 3: Enclosure Design & Final Layout

Enclosure Selection:

  • Material: Engineering plastic (e.g., PC/ABS) for lightweight, corrosion-resistant use, or metal (cold-rolled/stainless steel) for higher durability.

  • Protection Rating: The enclosure IP rating must meet or exceed the highest-rated socket installed (e.g., use an IP67 enclosure for an IP67 socket).

  • Size: Determined by the number of components and required wiring space; standard or custom sizes are available.

  • Mounting: Options include wall, pole, or flush mounting.

  • Features: Consider additions like viewing windows, locks, lifting lugs, internal lighting, or meters.

Drawing Approval:


The manufacturer provides an Electrical Schematic (circuit diagram) and a Component Layout Diagram for the enclosure. Verify all specifications, quantities, and arrangements before production begins.

Step 4: Manufacturing, Testing & Delivery

Assembly:


The enclosure is fabricated, and all components are installed and wired according to the approved drawings.

Factory Testing:

  • Electrical: Continuity, insulation resistance, dielectric strength, and operational tests (e.g., RCD trip) are performed.

  • Mechanical: Checks include enclosure sealing, door operation, and switch functionality.

Delivery:
Final deliverables include the product, user manuals, certification, test reports, and drawing copies. Logistics and shipping terms are confirmed.

Optional accessories to add

On the basis of high protection and durability, the Metal waterproof socket box can be upgraded from a basic distribution protection unit to a multifunctional intelligent control terminal that integrates distribution, monitoring, control, and safety warning by integrating multiple electrical components. Its main expansion capabilities are reflected in the following four aspects:

1. Status monitoring and display
Integrated current/voltage meter or display can monitor the electrical parameters of the circuit in real time, achieve visualization of power consumption, and facilitate overload prevention and fault diagnosis.

2. Core control and protection
Adding a contactor can achieve remote or automatic switching of the main circuit; Fuses provide reliable short-circuit and overload protection cores, together forming the core control and protection unit of the enclosure.

3. Safety warning and emergency stop
The phase indicator light can intuitively display the power status; The buzzer can sound an alarm in case of abnormality; The emergency stop button provides a quick power-off method in case of emergency, and the combination of the three greatly enhances operational safety and emergency response capabilities.

4. Modular integrated design
The above functional components can be flexibly and compactly integrated into the standard box through rail installation or reserved interfaces, achieving customized combinations of functions while maintaining the overall IP protection level.

Shell quality


High quality materials: Made of high-strength, corrosion-resistant cold-rolled steel plates, stainless steel (such as 304/316, used in highly corrosive environments), or aluminum alloy die-casting parts.
Surface treatment: Through processes such as degreasing, phosphating, and electrostatic spraying, a strong and adhesive anti-corrosion coating is formed. Outdoor models should have UV resistant coatings.
Box cover sealing: There is a high-quality silicone sealing gasket at the junction of the box cover and the box body, ensuring tight compression and long-term use without aging or cracking.
Sealing of inlet and outlet: equipped with waterproof cable gland (threading nut) or knock off hole+sealing ring to ensure that the cable is still sealed after being introduced
Plate thickness: The outer shell steel plate has sufficient thickness (such as ≥ 1.2mm) to ensure that the box is sturdy, impact resistant, and not deformed.
Door lock design: The lock has anti water accumulation design and local sealing to prevent water from seeping into the lock hole.
Grounding continuity: The shell has a dedicated grounding terminal and is reliably connected to the metal part of the box to ensure electrical safety.

Power on test of socket box

1. Division and functional testing

Step by step power transmission: First, turn on the main switch, then turn on the branch switches one by one (such as leakage protectors and air switches), and observe for any abnormalities (such as sparks or tripping).

Voltage verification: Use a multimeter to measure the voltage of each socket, confirm that the phase voltage (such as 220V ± 10%), phase sequence (if there are three-phase sockets) are normal, and the zero ground voltage is close to 0V.

Polarity test: Use a phase detector (voltage tester) to insert into each socket and confirm that the polarity of the wiring for "left zero, right fire, and grounding" is completely correct.

2. Protection function test

Leakage protection test: Pressing the "TEST" button on each leakage protector should immediately trip, proving the effectiveness of the leakage protection function.

Power on/off test: Operate each switch to confirm that it can control the power on/off of the corresponding socket normally.

3. Load testing and final inspection

Load operation: Connect actual loads (such as drills, light bulbs) or fake loads, run for a short period of time, and observe whether the sockets, switches, and lines have abnormal heating, noise, or voltage drop.
