Key Benefits

icon01.png
Dual-series coverage for all scenarios
Provides both ordinary power distribution type and variable-frequency control type to meet both terminal distribution and motor speed control needs.
icon02.png
High protection for harsh environments
The VFD control cabinet achieves an IP65 protection rating, is waterproof and dustproof, and can be directly used outdoors and in harsh industrial environments.
icon02.png
High-strength all-metal structure
Standing cabinets use 2 mm cold-rolled steel plate, wall-mounted boxes use 1.5mm cold-rolled steel plate, and the mitered integrated welding provides high strength.
icon02.png
Complete protection system
Integrates multiple protections including overcurrent, overvoltage/undervoltage, overload, phase loss and short circuit to ensure equipment safety.

Product Overview

GXL low-voltage distribution cabinet is a miniaturized intelligent terminal distribution device developed by NATUS Electric, including two major series: the ordinary power distribution cabinet and the GXL-VFD variable frequency drive control cabinet.The ordinary GXL low-voltage distribution cabinet is mainly used for power distribution and lighting supply, and is suitable for AC 500V and below three-phase four-wire / three-phase five-wire systems.
The GXL-VFD control cabinet is designed for motor start-stop protection and speed regulation. It is suitable for AC 50Hz systems with rated voltage below 690V and a maximum output power of 300kW. The low-voltage distribution cabinet adopts an all-metal semi-enclosed structure, fully complies with IEC 61439, GB 7251 and other international and Chinese standards, and is widely used in power plants, industrial and mining enterprises, civil buildings, petrochemical facilities and other scenarios.

Product Structure

The structure of the cabinet (box) adopts all-metal shell, which can be assembled by steel profiles or welded by thin steel plate bending; The installation mode of the cabinet (box) is standing cabinet (or hanging box), and the standing cabinet adopts 2mm high-quality cold-rolled steel plate and the hanging box adopts 1.5mm high-quality cold-rolled steel plate;
The electrical installation board inside the cabinet (box) can be removed separately; The inlet and outlet cables are introduced from the bottom. Users have special requirements, can also be in the box on the top of the cover plate to open into the line knock-down hole or add bus room;

Technical Advantages

01.
ram-line.png
Comprehensive electrical protection
Integrates overcurrent, overvoltage, undervoltage, overload, phase loss and short-circuit protection to effectively protect downstream motors and electrical equipment and reduce fault losses.
02.
