Overview
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.

Key Advantages
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.
