Product Description

XL-21 & GGD Series: The Foundation of Safe and Efficient Power Distribution

The XL-21 and GGD Series Low Voltage Power Distribution, Lighting, and Motor Control Cabinets are engineered to be the core workhorses of electrical distribution networks. Designed for versatility, durability, and uncompromising safety, these cabinets cater to a wide spectrum of applications, from factory floors and power plants to commercial buildings and outdoor infrastructure projects.

Core Functionality

Power Distribution: Receiving incoming electrical power (typically 400V AC 3-phase) and distributing it to multiple outgoing feeder circuits.
Lighting Control: Optimized for distributing and controlling lighting circuits, incorporating timer controls or contactors.
Motor Control: Equipped to house motor starters (DOL, Star-Delta, Soft Starters, VFDs) for controlling pumps, fans, and conveyors.
Circuit Protection: Integrates MCCBs, MCBs, Fuses, and RCDs to safeguard equipment against overloads and short circuits.
Isolation & Switching: Provides safe isolation points for maintenance and emergency shutdowns.

Factory Introduction

Key Design & Construction Features

1. Robust Enclosure

Constructed from high-quality, cold-rolled steel sheet with a rigid welded or bolted frame structure. Surface treatment includes electrostatic epoxy powder coating for excellent corrosion resistance.

2. Indoor/Outdoor Versatility

Specialized versions available for outdoor installation featuring enhanced sealing (IP54/IP55), roof overhangs, and UV-resistant coatings.

3. Modular Design

Utilizes standardized vertical sections and horizontal busbar chambers, allowing for easy configuration, expansion, and component replacement.
