This distribution terminal represents the high standards of modern electrical engineering, specifically configured as a "pre-reserved"

custom sub-distribution board. Unlike standard units, this low voltage distribution board is strategically designed to provide a

reliable electrical foundation for upcoming equipment, such as water treatment arrays. Housed in a premium steel enclosure, the

unit bridges the gap between the main grid and localized machinery. By deploying this electric distribution box, facility managers

ensure their systems possess excellent expansion potential while utilizing high-grade safety mechanisms to effectively reduce

downtime. This unit acts as a localized power hub, stabilizing current delivery to pumps and secondary devices, making it an

indispensable asset for high-demand building projects requiring modular scalability.



Core Components and Features

The internal architecture utilizes top-tier electrical components throughout. At its heart lies a high-breaking-capacity molded case

circuit breaker (MCCB), serving as the primary gatekeeper. This ensures the system can handle significant electrical surges without

compromising downstream equipment. The industrial electrical distribution panel features an organized layout of miniature circuit

breakers and leakage protection modules, creating a highly sensitive and safe electric distribution box.High-purity copper busbars

are utilized within the power supply cabinet to minimize thermal loss and optimize conductivity across all circuits. Furthermore, this

custom sub-distribution board includes dedicated terminal blocks and surge protectors (SPDs) to shield the entire floor-standing power

box from external electrical interference and atmospheric disturbances. Every component is clearly labeled with laser-etched tags,

facilitating rapid maintenance and ensuring the electric distribution box remains operational under rigorous industrial conditions. This

systematic arrangement allows for easy troubleshooting and ensures a longer lifespan for the internal 3-phase switching gear.



Design and Compliance

Design:

Constructed from high-strength, cold-rolled steel with a corrosion-resistant powder coating, this floor-standing power box is built to

withstand the vibrations and mechanical stresses of industrial pump rooms. The equipment adheres to IP54/IP55 standards, keeping

internal 3 phase power switchboard components shielded from dust and moisture. Such a robust exterior ensures this power supply

cabinet maintains its aesthetic and functional integrity over decades of service in humid or demanding utility environments.



Compliance:

Compliance is central to the design of this low voltage distribution board. It is manufactured in accordance with IEC 61439 and GB/T

7251 standards, making it a globally recognized industrial electrical distribution panel. Every custom sub-distribution board undergoes

rigorous dielectric and insulation testing before dispatch. By integrating certified CHNT components, the system guarantees predictable

performance and maximum operator protection. This commitment to safety ensures the electric distribution box provides total circuit

isolation when necessary for maintenance.
Future-Proof Scalability

This custom sub-distribution board allows for the immediate or delayed integration of pumps and filtration systems. By providing pre-

reserved circuit space, it eliminates the need for costly electrical overhauls as building facilities expand.



Superior Thermal Stability

By utilizing high-standard breakers within the 3 phase power switchboard, the unit minimizes nuisance tripping even under heavy load.

The industrial electrical distribution panel ensures the electric distribution box delivers a steady, uninterrupted current to critical

life-support systems.



Streamlined Maintenance

The floor-standing power box features a wide-angle door design and organized wire ducting. This allows technicians to inspect the XL-21

Power Distribution Cabinet efficiently, reducing human error during troubleshooting and enhancing the overall safety of the power supply

cabinet.



Space-Efficient Footprint

Despite its high capacity, the low voltage distribution board features a vertical design that saves valuable floor space in crowded utility

rooms. This compact 3 phase power switchboard allows for high-density power delivery without requiring extensive square footage.

Application Scenarios

Commercial Building Water Systems

The unit is expertly suited for high-rise buildings where it acts as a dedicated custom sub-distribution board for water supply. It manages

the energy for booster pumps and filtration units, serving as a reliable power supply cabinet that ensures constant water pressure across

all floors while protecting against motor overloads.



Industrial Wastewater Treatment

In manufacturing plants, this low voltage distribution board provides the necessary ruggedness to power aeration blowers and chemical

dosing pumps. As a heavy-duty industrial electrical distribution panel, it thrives in environments where constant operation is mandatory

and the 3 phase power switchboard must resist corrosive atmospheric elements.



HVAC and Cooling Tower Management

This electric distribution box can be extended to manage central air conditioning power needs. Acting as a floor-standing power box, it

distributes energy to cooling tower fans and circulation pumps, providing the localized circuit protection required for efficient thermal

management systems within large-scale complexes and data centers.



Municipal Infrastructure and Pumping Stations

Beyond buildings, the XL-21 Power Distribution Cabinet is an ideal solution for small-scale municipal drainage and irrigation projects. Its

role as a 3 phase power switchboard ensures that storm-water pumps receive consistent energy during peak demand. The custom sub-

distribution board configuration allows city engineers to reserve slots for emergency backup systems, making the electric distribution box

a versatile tool for long-term public utility resilience and maintenance.
