AllSpark Modular Midi Fuse Holders – Compatible with Bussmann LMI System

The AllSpark Modular Fuse Holder system delivers heavy-duty, reliable DC circuit protection in a compact, modular format. Fully compatible with Bussmann LMI “Little Block” fuse panels, this AllSpark-designed system offers seamless integration with existing setups or a complete solution when building from scratch.

Built to the highest standards, the AllSpark system features:

• AllSpark Input Module – Accepts a high-current main input from your battery via a 5/16" (M8) stud connection.

• AllSpark Modular Fuse Holders (this listing) – Each holder accepts a standard Midi/AMI fuse up to 200A.

• Modular Busbars – Available in 3 to 7-hole configurations to suit systems with 2–6 fuse holders.

These components clip together to form a secure, customisable multi-circuit fuse block, ideal for protecting high-current devices such as inverters, DC chargers, and solar regulators. Simply configure the number of fuse holders required and connect them using the busbar to the central input module.

Key Features:

• 100% compatible with Bussmann LMI Midi Fuse Holders

• Rated up to 200A per fuse holder (total busbar current up to 400A)

• Accepts industry-standard Midi/AMI fuses (30A to 200A)

• 3/16” (M5) studs with nuts on fuse holders – use with lugs with 5–6mm eyelets

• Durable design for harsh environments – ideal for automotive, marine, and industrial use

• Clip-together modular design for flexible system expansion

Recommended Setup:

• 1 × AllSpark Input Module (for incoming battery connection)

• 2–6 × AllSpark Fuse Holders (one per protected circuit)

• 1 × AllSpark Busbar (1 hole for input, 1 per fuse holder)

• 2–6 × Midi/AMI Fuses (30–200A)

Alternatively, you can purchase individual fuse holders separately for standalone inline circuit protection—ideal when a full block isn’t required.

Perfect For:

• Dual battery setups

• Inverter cabling

• DCDC chargers

• Caravan & 4WD solar systems

• Marine & boating applications

• Agricultural and commercial vehicle wiring

• Heavy transport and specialty builds

AllSpark Midi/AMI fuses are available separately in 30A, 40A, 50A, 60A, 70A, 80A, 100A, 125A, 175A, and 200A sizes.

Backed by Offroad Living’s commitment to quality and compatibility, the AllSpark Modular Fuse Holder system is the smart choice for safe and efficient power distribution.
