CNP820H-3P White Junction Box – 3 Pole 10A 250V Cable Connection Solution

TheCNP820H-3P White Junction Box is a compact electrical cable connection box designed for three-pole wiring applications. It provides a dedicated space for cable connection and organization, helping keep electrical wiring more structured and protected inside the housing.

As part of the WHITE JUNCTION BOX series, CNP820H-3P combines a compact white PP housing with a practical cable connection structure. According to the product specifications, this model is rated for 10A current and 250V voltage and supports a wiring range of 3×1.5mm². The housing material is PP, while the tail tube is made of PVC, with an inner diameter of 7.5mm.

Product Specifications

3-Pole Cable Connection

The CNP820H-3P is designed with a 3-pole connection structure, making it suitable for wiring applications that require three connection paths within one compact junction box.

Compared with a 2-pole version, the 3-pole configuration provides an additional connection position for applications requiring three conductors. This makes the product suitable for different electrical wiring arrangements where several wires need to be organized within the same connection area.

The three internal connection positions are arranged in a compact layout, helping reduce unnecessary wire clutter and keeping the connection area more organized.

10A and 250V Electrical Rating

The CNP820H-3P has a rated current of 10A and a rated voltage of 250V. These specifications make it suitable for electrical wiring applications that fall within the stated electrical rating of the product.

The product should be selected according to the actual electrical load, cable specification and installation requirements of the application. Using the correct cable size and ensuring proper installation are important for maintaining a reliable electrical connection.

3×1.5mm² Wiring Range

The specified wiring range for CNP820H-3P is 3×1.5mm². This means the product is designed for a three-wire configuration using 1.5mm² conductors according to the product specification.

This wiring configuration makes the junction box suitable for many compact electrical connection applications where three conductors need to be brought together in one connection point.

For installers and equipment manufacturers, the clearly defined wiring specification also makes it easier to select the appropriate model before installation.

PP Housing Material

The outer housing of the CNP820H-3P is made from PP material. The white housing provides a clean appearance while forming the external enclosure around the internal connection area.

The product information also highlights the use of a new PP material shell, with features including insulation performance, durability and resistance to high temperatures.

The compact housing is designed to provide a practical enclosure for the cable connection while maintaining a relatively small installation footprint.

PVC Tail Tube

The CNP820H-3P uses a PVC tail tube at the cable entry section. The specified inner diameter of the tail tube is 7.5mm.

The tail tube provides a transition area between the incoming cable and the junction box. It helps guide the cable toward the internal connection area and contributes to a cleaner cable arrangement.

This structure is particularly useful when the cable needs to enter the junction box from a defined direction.

Compact Structure and Dimensions

According to the product drawing, the CNP820H-3P has a wire box height of 11mm. The main box dimension shown in the drawing is 42.7mm, while the cable extension dimension is 72mm. The drawing also indicates Φ3andΦ10 hole dimensions.

These compact dimensions make the CNP820H-3P suitable for applications where installation space is limited.

The relatively compact housing can help equipment manufacturers and installers arrange cable connection points without taking up unnecessary space.

Enclosed Connection Design

The CNP820H-3P uses an enclosed housing structure with a cover. Once the wiring connection is completed, the cover can be closed over the connection area.

This design helps create a cleaner finished installation compared with leaving individual connection points exposed. It also keeps the internal connection components concentrated within the designated housing.

For equipment assembly and electrical installation work, an organized connection area can make cable routing and subsequent inspection more convenient.

White Junction Box for Electrical Wiring

The white housing gives the product a simple and clean appearance, making it suitable for various electrical equipment and wiring environments.

TheWHITE JUNCTION BOX series is designed around compact cable connection solutions. CNP820H-3P provides a three-pole option for projects where three conductors need to be connected and organized in a compact housing.

The product can therefore be considered for applications such as electrical wiring, lighting equipment, distribution wiring and internal equipment connections, provided the application remains within the specified 10A, 250V and 3×1.5mm²ratings.

Flame-Retardant and Insulating Material

The product information for the WHITE JUNCTION BOX series highlights a 94V-2 flame-retardant rating and describes the housing as providing insulation and environmental protection characteristics.

The PP housing is also presented as having good insulation, durability and high-temperature resistance characteristics.

These material characteristics make the housing suitable for electrical connection products where insulation and material performance are important considerations.

Applications

TheCNP820H-3P White Junction Box can be used in a range of electrical wiring applications, including:

• Electrical cable connections
• Lighting wiring
• Electrical equipment wiring
• Cable distribution
• Internal equipment wiring
• Compact electrical installations
• Three-wire connection applications
• Electrical maintenance and wiring projects

For each application, the actual operating conditions, cable size and electrical load should be checked against the product specifications.
