⚡ At a Glance
- • Current Capacity: Rated for very large currents, up to 600A using a tinned brass strip
- • Best for: Wiring in cars, ships, motorhomes and other 12–48V DC systems
- • Not ideal for: AC mains distribution or circuits outside the 12–48V DC range
A four-stud bus bar built from a high-current tinned brass strip and mounted on an ABS flame retardant plastic base. Stainless steel screws and nuts improve mechanical strength and resistance to corrosion for demanding DC applications.
Safe high-current distribution – thanks to a 600A tinned brass strip
High-current capability comes from a thick, tinned brass conductor designed for low impedance and strong mechanical strength. Tinning improves surface conductivity and offers some protection against oxidation.
Capable of handling heavy loads in vehicle and marine electrical systems without excessive voltage drop. Suitable where reliable DC power distribution is required for starters, winches or auxiliary battery banks.
Corrosion resistance in harsh environments – with stainless steel fasteners and tinned conductor
Stainless steel screws and nuts resist rust, while the tinned brass strip reduces the chance of corrosion on contact surfaces. An ABS flame retardant base adds electrical isolation and mechanical protection.
Durable connections that tolerate damp or salty conditions found on boats and coastal vehicles. Fewer maintenance visits and more consistent electrical performance over time.
Neat, space-saving wiring – with a multi-layer composite modular connection
A multi-layer composite structure provides repeatable electrical paths and low impedance across multiple studs, while keeping connections consolidated in a compact footprint.
Simplifies wiring looms and reduces clutter in electrical bays, making routine checks and expansions quicker. Multiple circuits can be organised centrally without sacrificing reliability.
