Overview

Panelboard – UL67, also known as a Low Voltage Distribution Panelboard, is an important low-voltage electrical distribution product used to distribute power from an upstream switchboard, switchgear, transformer, or main distribution panel to multiple branch circuits. It is commonly used in commercial buildings, residential buildings, industrial facilities, schools, hospitals, office buildings, public infrastructure, and other low-voltage power distribution systems.

In a complete electrical distribution system, the panelboard is usually installed downstream of low-voltage switchgear or low-voltage switchboards. While LV Switchgear and LV Switchboard are mainly used for main power distribution or larger feeder distribution, the panelboard is more commonly used for final distribution or branch circuit distribution. It can distribute power to lighting circuits, socket circuits, HVAC control circuits, small power loads, equipment feeders, and other electrical loads.

Panelboard – UL67 can be designed for lighting distribution and power distribution applications. A lighting panelboard is typically configured with a main molded case circuit breaker and miniature circuit breakers or branch circuit breakers for outgoing circuits. A power distribution panelboard can be configured with a main MCCB and feeder MCCBs to provide protection for larger branch loads. Depending on the project requirements, the panelboard can support bolt-on, plug-on, rail-type bolt-on, or plug-in breaker arrangements.

The product is designed for low-voltage distribution systems where safety, compact structure, convenient wiring, reliable protection, and easy maintenance are important. It can be supplied as a wall-mounted or floor-mounted enclosure depending on size and project requirements. The panelboard can also be customized according to rated voltage, rated current, number of circuits, breaker type, enclosure size, cable entry direction, neutral and grounding bar configuration, metering requirements, and installation environment.

For international projects, Panelboard – UL67 is a practical product for customers who need low-voltage final distribution equipment with flexible circuit arrangement and reliable branch protection. It is suitable for both new construction and electrical renovation projects. It can be integrated with LV Switchgear, UL 891 Switchboards, dry-type transformers, and complete unit substation systems.

Product Advantages

1. Reliable Low-Voltage Final Distribution
Panelboard – UL67 is designed to distribute low-voltage power to multiple final circuits. It is suitable for lighting, socket outlets, HVAC systems, small equipment loads, and other branch circuits. It helps organize the downstream electrical network and provides individual circuit protection for different loads.

2. Suitable for Lighting and Power Distribution
The product can be configured as a lighting panelboard or a power distribution panelboard. Lighting panelboards are suitable for lighting and small branch circuits, while power distribution panelboards are suitable for feeders and larger branch loads. This flexibility allows the product to meet different project requirements.

3. Flexible Breaker Configuration
The panelboard can be equipped with molded case circuit breakers, miniature circuit breakers, or other branch protection devices according to system design. For lighting panelboard applications, the main device can be an MCCB and outgoing feeders can be MCBs. For power distribution panelboard applications, both the main device and feeders can use MCCBs.

4. Bolt-On and Plug-On Options
Different breaker installation methods can be selected according to project requirements. Bolt-on breakers provide secure mechanical connection and are often used in commercial and industrial environments. Plug-on or plug-in structures can improve installation convenience and make circuit replacement faster in suitable applications.

5. Compact Structure and Space Saving
Compared with larger switchgear and switchboards, panelboards are more compact and easier to install in electrical rooms, corridors, utility areas, equipment rooms, and building distribution zones. The compact design helps save installation space and supports flexible building electrical layouts.

6. Convenient Installation and Maintenance
The panelboard structure is designed for convenient cable termination, breaker installation, inspection, and maintenance. Clear circuit arrangement and accessible internal layout help electricians complete wiring and maintenance efficiently. This is especially important for commercial buildings and facilities with many branch circuits.

7. Safe Enclosure and Internal Protection
The panelboard can be designed with a protective enclosure to reduce accidental contact with live parts. IP20 finger-safe protection and suitable internal separation options can be selected according to project requirements. Proper enclosure design helps improve operator safety during installation and maintenance.

8. Customizable Circuit Arrangement
The product can be customized based on the number of outgoing circuits, circuit breaker ratings, main breaker size, busbar capacity, neutral bar, grounding bar, metering requirement, surge protection, and cable entry direction. This makes it suitable for different building layouts and electrical design requirements.

9. Wide Range of Applications
Panelboard – UL67 is suitable for commercial, industrial, residential, public, and infrastructure applications. It can be used for lighting distribution, branch power distribution, equipment feeder protection, utility room distribution, floor distribution, and tenant distribution.

10. Easy Integration with Complete Distribution Systems
The panelboard can work with upstream LV Switchgear, LV Switchboards, transformers, generators, and power monitoring systems. It is an important part of a complete low-voltage distribution network, helping deliver power safely from main distribution equipment to final electrical loads.
