XL-21 Low Voltage Power Distribution Cabinet

Complete integrated monitoring & control panel, fitted with 4 sets of analog meters, running indicator lights and main isolation switch, enabling operators to check voltage and current data directly without extra testing tools. The cabinet body is made of 1.5mm thick cold rolled steel, treated by electrostatic spraying to resist rust and scratch, with service life over 10 years under normal indoor environment.

Optimized bottom & side dual heat dissipation louver design, which effectively discharges heat generated by internal busbars and electrical components, avoiding high temperature failure during 24-hour continuous full-load operation. Independent separated wiring channels are reserved inside to separate strong and weak wires and reduce circuit interference risks.

Safe lockable door structure with professional electric hazard warning label, preventing irrelevant personnel from opening the cabinet by mistake. The door is equipped with interlocking protection, which can cut off power supply automatically when the door is opened live, greatly lowering electric shock risks for maintenance workers.

Strong internal expandability, users can freely install circuit breakers, contactors, leakage protectors and soft starters according to actual load power. All copper busbars are tinned with high conductivity and low heat loss, supporting rated current from 100A to 2000A for different power demands.

Full compliance with CE international low voltage electrical standards, all built-in electrical components pass related safety certifications. We support customized cabinet size, surface anti-corrosion treatment and internal circuit layout for humid, coastal and chemical workshop environments, with complete installation accessories delivered together.

◉ Factory production workshop: This XL-21 power cabinet serves as central power distribution equipment for assembly lines, motors, processing machines and workshop lighting, realizing real-time monitoring of power consumption and independent loop protection for each production zone.

◉ Construction engineering projects: Widely used for temporary power supply of construction sites, providing stable power for tower cranes, elevators and construction machinery with complete short-circuit and overload protection functions.

◉ Commercial & municipal buildings: Suitable for shopping malls, office buildings, schools and hospitals to distribute power for air conditioning, elevators and public lighting, with visual meter panel for convenient daily power inspection.

◉ Light industry & small chemical plants: After customized anti-corrosion surface treatment, it can work stably in slightly corrosive workshops to control power of packaging, printing and processing equipment.

Check all internal wiring and component fastening before power-on. Close and lock the cabinet door after confirming no circuit faults. Observe voltage and current data via front meters during operation. Download the full PDF operation manual for wiring diagrams, component replacement and routine maintenance steps.

Can the internal electrical layout of XL-21 power cabinet be customized?

Yes, we can adjust the quantity of breakers, contactors and busbars according to your actual load, and provide free professional electrical layout drawings before production to match local power standards.

What's the heat dissipation performance of this XL-21 distribution cabinet?

It adopts double heat dissipation louver structure at bottom and sides, which can rapidly discharge internal heat. It can run stably under full load for 24 hours without overheating inside the cabinet.

Does this XL-21 cabinet meet EU export requirements?

The whole cabinet and all internal electrical parts have obtained CE certification. We can offer complete certification documents for customs clearance, and support customized voltage specifications for different countries.
