Surface Mount Low Voltage Indoor Distribution Box 3 Phase Electric Control Panel

The Low Voltage Indoor Distribution Box is a premium electrical hub designed for safe and efficient power management in residential, commercial, and industrial settings. Operating on 3-phase AC systems, this control panel serves as the central point for housing miniature circuit breakers (MCBs), residual current devices (RCDs), and surge protectors.

Engineered with high-grade cold-rolled steel or flame-retardant ABS (depending on the model), our distribution boxes offer a sleek, low-profile design that blends into indoor environments while providing rugged protection for your internal switchgear. Whether you are wiring a luxury apartment complex or a small manufacturing workshop, this panel ensures organized cable management and easy access for maintenance.

• High-Grade Material Options: Available in electro-galvanized steel with an epoxy powder coating (for durability) or impact-resistant PC/ABS (for lightweight, non-corrosive indoor use).

• Modular "DIN Rail" System: Features standard 35mm adjustable DIN rails, making it compatible with all major global brands of circuit breakers and modular components.

• Superior Cable Management: Spacious internal wiring gutters and removable gland plates (top and bottom) allow for clean, rapid installation of multi-core 3-phase cables.

• Safety & Ingress Protection: Rated up to IP40, providing protection against solid objects and accidental contact. Includes a dedicated copper earthing (PE) and neutral (N) bar for stable grounding.

• Reversible Transparent Door: The high-strength polycarbonate door allows for easy inspection of breaker status without opening the panel, and can be mounted to open from either the left or right.

1. Residential Complexes: Centralized branch circuit protection for high-rise apartments and luxury villas.

2. Commercial Offices: Managing lighting, HVAC, and server room power distribution in modern office layouts.

3. Industrial Workshops: Compact control panels for small machinery, air compressors, and localized power points.

4. Retail & Hospitality: Organized electrical control for shopping malls, hotels, and restaurant kitchens.

• Anti-Corrosive Finish: Our metal boxes undergo a multi-stage pickling and phosphating process, ensuring they remain rust-free even in humid indoor climates.

• Heat Dissipation Design: Optimized internal volume and ventilation slots prevent heat buildup from densely packed circuit breakers, extending the life of your switchgear.

• Secure Locking Mechanisms: Available with plastic latches or key-lockable metal handles to prevent unauthorized tampering in public areas.

• Labeling & Identification: Comes with pre-printed circuit identification strips and directory cards for professional, code-compliant labeling.

Q: Can this box be used for both 1-Phase and 3-Phase wiring?

A: Yes. While designed for 3-phase systems, the internal busbar and terminal arrangements can easily be configured for 1-phase distribution if required.

Q: Is the mounting plate adjustable?

A: Yes, the internal DIN rail assembly can be adjusted in depth to accommodate different breaker heights and to ensure a flush fit with the front cover.

Q: Does it come with the circuit breakers included?

A: As a standard, we provide the empty enclosure with busbars and terminals. However, we offer "fully populated" custom panels pre-fitted with MCCBs or MCBs based on your specific project requirements.

XL-21 Low-voltage power distribution cabinet is suitable for power distribution of three-phase four-wire or three-phase five-wire system with AC voltage of 500 volts and below in power plants and industrial and mining enterprises. XL-21 low-voltage power distribution cabinet is installed against the wall of the indoor device, and inspected in front of the screen. The shell IS made of steel plate bending, and the knife switch handle is on the upper part of the right column in front of the box, which can be used for switching power supply. According to the needs of users, different types of circuit breakers with different current levels can be selected to meet the needs of different users.
