The MB-AF series distribution box is a modular, flame-resistant ABS enclosure designed for AC circuits, offering multiple port configurations and easy installation for industrial and commercial applications.

Overview

The MB-AF distribution box is a modular distribution board primarily used in AC 50Hz circuits with rated voltages of 220V/380V. It is designed to house modular combination equipment and is widely applied in residential, commercial, and industrial settings, including high-rise buildings, stations, ports, airports, hospitals, cinemas, and enterprises . The enclosure is made of flame-proof, impulse-proof ABS plastic, providing excellent insulation and compliance with standards BS EN60439-3 and JB/T7121-93 .

Features

• Material: Flame-resistant ABS plastic for safety and durability .
• Design: Fashionable door with elegant appearance and reasonable structure; easy installation and dismounting .
• Modularity: Supports modular combination equipment, allowing flexible expansion and interchangeability .
• Port Configurations: Available in 6-way, 8-way, 12-way, 16-way, 24-way, and 36-way versions, accommodating various circuit requirements .
• Dimensions: Example dimensions include H1: 59–60 mm, H2: 73–74 mm, H3: 99.5–103 mm, L: 185–314 mm, W: 141–428.7 mm depending on the number of ways .

Applications

• Industrial automation: Connecting sensors and actuators to controllers, especially in harsh environments with exposure to refrigerants or lubricants .
• Power and signal distribution: Ensures reliable decentralised signal and power transmission, with protection up to IP67 in some industrial variants .
• HVAC systems: Compatible with indoor units in VRF systems, allowing multiple units to connect to a single port in Air Flux switch boxes .

Advantages

• Compact and lightweight: Facilitates installation in tight spaces .
• High protection and durability: Encapsulated housing resists shock, vibration, and environmental stress .
• Flexible configuration: Multiple port options and modular design allow customization for specific applications .
• Compliance with standards: Ensures safety and reliability in electrical installations . The MB-AF distribution box is therefore a versatile solution for modular power and signal distribution, suitable for both industrial automation and commercial electrical installations, providing safety, flexibility, and ease of installation.
