Product Overview

Our Indoor 3-Phase Low-Voltage Distribution Box is a versatile and robust solution for centralized power management in commercial, industrial, and residential buildings. Engineered for systems up to 690V, this steel distribution cabinet serves as the primary hub for housing circuit breakers, surge protectors, and metering equipment.

Constructed from high-quality cold-rolled steel with a precision-powder-coated finish, these boxes are built to withstand the rigors of high-traffic electrical rooms. The modular internal design supports standard DIN-rail components or customized mounting plates, ensuring a clean, organized, and safe installation. Whether you are managing a small office floor or a large-scale factory workshop, this distribution board provides the structural integrity and electrical safety required by modern standards.

Key Technical Advantages

• High-Strength Steel Construction: Fabricated from 1.2mm to 2.0mm cold-rolled steel with a corrosion-resistant electrostatic epoxy finish. This ensures the cabinet remains rigid and rust-free even in humid indoor environments.

• Modular DIN Rail System: Equipped with adjustable 35mm DIN rails, making it compatible with all major brands of MCBs, RCCBs, and RCBOs (such as ABB, Schneider, and Chint).

• Advanced Safety Grounding: Features a dedicated copper earth bar and pre-welded grounding studs on both the door and the body, ensuring maximum protection against electrical faults.

• Flexible Cable Entry: Designed with removable top and bottom gland plates, allowing for easy drilling to accommodate various conduit and cable sizes without compromising the enclosure's integrity.

• Ergonomic Door Design: The 120° wide-opening door is fitted with a heavy-duty cam lock and high-elasticity sealing strips to prevent dust ingress and accidental contact with live components.
