It is purpose-built for power reception, distribution and motor control in end-use power supply scenarios. Featuring a space-saving enclosed structure, dependable electrical performance and straightforward operation, it delivers a cost-effective distribution solution for small-to-medium industrial, commercial and municipal projects.
Core Features
-
Robust Enclosed Construction
Fabricated from high-quality cold-rolled steel with precision forming and surface treatment, the cabinet delivers high mechanical strength and corrosion resistance. With a standard IP30 protection rating, it effectively blocks solid foreign objects larger than 2.5mm, ensuring safe, stable operation in indoor industrial and commercial environments.
-
Flexible Customizable Configuration
It supports flexible assembly of various low-voltage components, including molded case circuit breakers, AC contactors, thermal relays, fuses and metering devices. Internal circuits can be fully tailored to match specific load requirements, realizing functions such as power distribution, motor start-up control, overload/short-circuit protection and power metering.
-
Easy Installation & Maintenance
Featuring a front-access design with fully openable doors, it enables convenient wiring, component replacement and routine inspection. Its compact footprint saves installation space, making it ideal for deployment in small distribution rooms, on-site workshops and space-constrained locations.
-
Comprehensive Safety Protection
Built with complete overload, short-circuit and optional earth-leakage protection functions. The internal layout follows standard electrical clearance and creepage distance requirements, effectively reducing electrical fault risks and safeguarding both operators and connected equipment.
-
Cost-Effective Universal Solution
As a mature and widely standardized terminal distribution product, the XL-21 series offers stable performance, highly universal spare parts and low maintenance costs. It adapts to diverse end-use power demands, providing an economical and reliable power distribution option for various applications.
