The 150A 2-Stud Negative Busbar provides a reliable common connection point for high-current negative cables.
Instead of stacking multiple cable lugs directly onto a battery terminal, the busbar allows the battery negative and equipment return cables to be connected at a dedicated distribution point. This helps produce a cleaner installation that is easier to inspect, maintain and expand.
Both M10 studs are electrically connected through the internal nickel-plated brass bus, allowing current to pass between the connected circuits. Built for high-current 12V systems
With a continuous current rating of up to 150A, this busbar is suitable for demanding auxiliary-power installations, including:
- Dual-battery systems
- Lithium battery installations
- DC–DC chargers
- Inverters
- Canopy power systems
- Solar and off-grid systems
- Caravan and camper electrical systems
- Marine and automotive applications
The compact surface-mount design makes it particularly useful where installation space is limited.
