1. Patented Staggered 5-hole Design

The two-hole and three-hole sockets adopt a 45° staggered layout with a hole spacing of 44mm, solving the problem of mutual interference of plugs in traditional 5-hole sockets, and can insert two standard plugs at the same time (e.g., mobile phone charger + computer power supply).

3. Structural and Process Advantages

Honeycomb Back Structure: Enhance mechanical strength, high temperature resistance and impact resistance, no deformation after long-term use.

G3 Curvature Chamfered Frame: Round design, improve hand feel and reduce collision risk.

Tool-free Wiring: Quick connection terminals, compatible with 1.5-2.5mm² wires, easy installation.

Independent Fixing Frame: 850℃ high-temperature flame-retardant fixing frame, ensure firm installation.

1. Application Scenarios and Load Compatibility
2. Applicable Load Types

Low-power equipment: Mobile phone chargers (5-100W), routers (10-20W), desk lamps (5-60W)

Medium-power equipment: Laptops (60-120W), printers (30-100W), monitors (20-50W)

Restriction: It is prohibited to connect equipment ≥ 2200W (e.g., electric water heaters, air conditioners, induction cookers, etc.), 16A three-hole sockets should be selected (e.g., A3T326 series)

2. Recommended Installation Positions

Living room: Both sides of the sofa, TV background wall (300mm from the ground)

Bedroom: Both sides of the bed (700mm from the ground), dressing table

Kitchen: Above the operation counter (1200mm from the ground, splash-proof box required)

Bathroom: Dry area (above 1500mm from the ground, IP44 splash-proof socket required)

1. Installation and Wiring Specifications
2. Pre-installation Preparation

Confirm that the depth of the back box is ≥ 50mm, and the interior is clean and free of debris.

Select 2.5mm² copper-core rigid wires (BV wires) to ensure that the wire diameter meets the 10A current requirement.

Power-off operation: Turn off the circuit breaker of the corresponding loop and verify that there is no voltage.

2. Standard Wiring Method (Neutral on Left, Live on Right, Ground on Top)

3. Key Installation Points

-The wire stripping length is about 8-10mm to avoid short circuit caused by excessively long exposed conductors.

The screw torque is controlled at 1.2-1.5N·m to prevent damage to terminals or wires.

The horizontal installation error of the panel is ≤ 1° to ensure aesthetics and use comfort.

Test after installation: Use an electric tester to check the correctness of phase line/neutral line/grounding wire connection, and test the function of the protection door.

VII. Selection and Alternative Solutions

1. Same-series Alternatives

16A three-hole socket: A3T326 (suitable for high-power equipment such as air conditioners and electric water heaters)

5-hole socket with switch: A3T426K (added single-pole switch to realize one-key power-off)

Double socket: A3T426U2 (double 5-hole design, increase power supply interfaces)

2. Cross-series Upgrades

Extol Series: A5T426 (ultra-thin design, narrower frame)

Essential Series: A1T426 (cost-effective model with complete basic functions)

VIII. Important Safety Tips

1. This socket is exclusively for single-phase 220V, and it is strictly prohibited to connect to three-phase 380V power supply.
2. Splash-proof sockets with protection class IP44 or above should be selected for humid environments such as bathrooms and kitchens.
3. Do not connect too many high-power devices to the socket to avoid fire caused by overload.
4. Regularly check the status of the socket, and replace it immediately if abnormalities such as cracks, discoloration and heating are found.

2. Selection by Scenario

Living room/Bedroom: Priority is given to Avant-garde A3T426 or Extol A5T426, with staggered 5-hole design and beautiful appearance, suitable for simultaneous use of multiple devices.

Kitchen/Bathroom: Additional IP44 splash-proof box is required, and sockets with higher protection class are recommended.

Industrial project/Bulk procurement: Essential A1T426 or Chint 6C to balance cost and quality.

Children’s room: All series are required to have child protection doors, and priority is given to the enhanced protection design of Avant-garde/Extol.

2. Selection by Priority Demand

3. Priority	Recommended Products	Reasons
   Safety First	Avant-garde A3T426/Extol A5T426	850℃ flame retardant, grounding priority, anti-single-pole insertion
   Appearance First	Extol A5T426	Ultra-thin frameless design + one-key cover replacement, strong design sense
   Cost Performance First	Essential A1T426/Chint 6C	Complete basic functions, affordable price
   Practicality First	Avant-garde A3T426	Patented staggered 5-hole design, solving the pain point of plug interference

4. Key Notes
5. All 10A sockets are strictly prohibited to connect to equipment ≥ 2200W (e.g., air conditioners, electric water heaters), and 16A three-hole sockets should be selected (e.g., Schneider A3T326).
6. IP44 or higher splash-proof boxes must be installed in humid environments (bathrooms/kitchens) to avoid electric leakage risks.
7. Strictly follow the “neutral on left, live on right, ground on top” specification during wiring, and control the wire stripping length at 8-10mm.
8. Be sure to test after installation: check the correctness of wiring with an electric tester + test the function of the protection door.
