Product Overview
The XL-21 is a classic power distribution solution that features a fully enclosed structure. The frame is typically welded or assembled using high-quality steel profiles, providing a rigid and dust-proof enclosure. It is designed for front-door operation and maintenance, making it suitable against walls or in centralized distribution rooms. Its simplicity and durability make it one of the most widely used low-voltage cabinets for power loads under 630A.
Product Features
- Robust Enclosure: The cabinet is made of cold-rolled steel plates with a thickness designed to withstand mechanical stress and environmental factors.
- Safety & Protection: Provides a standard protection rating of IP30, effectively preventing the ingress of solid foreign objects and ensuring operator safety.
- Component Versatility: Can be equipped with various types of circuit breakers (MCCB), knife switches, and fuses depending on the specific electrical scheme.
- Simplified Maintenance: The wide-opening front door provides easy access to all internal components, busbars, and cable terminals for routine inspections.
- Compact Design: Optimized internal layout allows for high circuit density within a relatively small floor footprint.
Technical & Artistic Details
The XL-21 balances industrial functionality with a professional aesthetic suitable for modern facilities.
- Surface Treatment: All metal components undergo a multi-stage cleaning and phosphating process before being finished with high-quality electrostatic powder coating for excellent corrosion resistance.
- Reliable Grounding: A dedicated grounding busbar runs through the cabinet, ensuring a low-impedance path to earth for all internal equipment.
- Heat Management: Designed with natural convection in mind, ensuring stable operation of electrical components within standard temperature limits.
