6 Way Bolt Fuse Holder | MEGA MIDI Automotive Power Distribution Box

그만큼 6 way bolt fuse holder is a high-current centralized power distribution module designed for automotive and new energy electrical systems. This 6 way bolt fuse holder adopts reinforced PA66 flame-retardant housing paired with high-conductivity brass terminals, delivering stable power distribution and reliable overcurrent protection for multi-circuit low-voltage DC systems. With IP66 waterproof rating and bolt-down stud structure, it performs reliably even in harsh environments such as engine compartments, chassis mounting and outdoor equipment, and is widely used in electric vehicles, RVs, modified cars, engineering machinery and industrial control cabinets.

Core Features of MEGA MIDI Automotive Fuse Box

• 6 independent circuits, realizes centralized protection of main power supply and multiple branch circuits in one unit
• Main circuit uses M8 studs, compatible with MEGA series bolt-down fuses (30A-650A, 12V-80V DC)
• Branch circuits use M5 studs, matching MIDI series bolt-down fuses (30A-200A, 12V-58V DC)
• Housing made of PA66 engineering plastic, UL94 V-0 flame retardant grade, meets automotive fire safety standards
• Brass conductive terminals, low contact resistance, stable current carrying performance under long-term high load
• IP66 ingress protection, effectively blocks dust and high-pressure water spray, suitable for engine bay and under-chassis installation
• Equipped with transparent protective cover, visual fuse status inspection without opening the cover, while isolating dust and moisture
• Bolt-down stud structure, strong anti-vibration performance, adapts to long-term driving vibration conditions

Compared with ordinary blade fuse boxes, this bolt-down power distribution unit supports much higher current capacity and better anti-vibration performance. Its modular design separates the main circuit from branch circuits, which simplifies wiring layout, reduces line loss, and greatly improves the safety and maintainability of the entire electrical system.

Main Technical Specifications

Selection & Installation Guide

When selecting a 6 way bolt fuse holder, first confirm the system total current, branch circuit quantity and working voltage. Select corresponding MEGA and MIDI fuses according to the actual load of each circuit, and reserve a 1.25-1.5 times safety margin for current rating to avoid overheating under long-term operation. For installation in engine compartments or under chassis, IP66 rated models are required to cope with water spray and dust environments. During installation, control the tightening torque of M5 and M8 studs properly to avoid thread slipping or housing cracking. Reasonably distribute the load of each branch to avoid exceeding the total 240A continuous current limit.

Application Scenarios

• Electric vehicles, hybrid vehicles and new energy on-board power distribution systems
• RVs, travel trailers and camper van electrical system protection
• Automotive modification projects and high-power car audio systems
• Heavy trucks, engineering construction machinery and agricultural equipment
• Off-grid solar energy storage systems and auxiliary power units
• Marine and yacht DC power distribution cabinets
• Industrial control cabinets and mobile power supply equipment

Usage & Maintenance Notes

1. Select fuses with correct current and voltage ratings according to the actual load of each circuit, and do not use fuses exceeding the specification.

2. Tighten the terminal nuts with standard torque to ensure sufficient contact area and avoid overheating caused by loose connections.

3. Although the product has IP66 protection, avoid long-term immersion in water to ensure service life.

4. Disconnect the main power supply before replacing fuses or wiring to avoid electric shock and short circuit damage.

5. Regularly check the terminals for oxidation, looseness or overheating signs, and clean and maintain them in time.

6. Keep the transparent cover properly installed during daily use to maintain the expected dustproof and waterproof performance.
