INMEGA Series In-Line Mega Fuse Holder

For superior overload protection, GEP Power Products has designed bolt-down style IN-LINE Littelfuse™ MEGA® fuse holders.



  • Fasteners are cemented with LOCTITE to assure assembly durability
  • Assembled with torque controlled tools
  • Over-molded cover protects against mechanical stress
  • Tamper evident overmold cover option is available to protect against unauthorized fuse bypass

In rugged environments, dust, dirt, water, abrasion and mechanical abuse can be extremely detrimental to electrical systems. Lack of protection from these elements frequently causes shorts in vehicle electrical systems causing damage to costly peripherals. Older style fuse designs do not protect wires from abrasion in rough terrain. GEP Power Products’ IN-LINE Littelfuse™ INMEGA® Fuse Holders are custom designed with an over-molded PVC covering that is rated IP67.


To protect power systems in transportation and off-road equipment, fuses are incorporated into power cords and wiring systems for the following uses:

  • Alternator connections
  • Battery connections
  • Other heavy-duty cables that require high current protection


Mega fuse holders are used as sacrificial devices in many OEM vehicle electrical systems:

  • Agricultural Equipment
  • Commercial Lawn Care Equipment
  • Construction Equipment
  • Golf Carts
  • Military Vehicles
  • Off-Road Vehicles
  • Over-the-Road Transportation
