12V 300A 4M6+12M4 Studs Power Distribution Terminal Bus Bar Marine Grade

Bus Bar 12V 300A 4M6+12M4 Studs Marine Battery Automotive Boat

Description:

Heavy-Duty 300A Power Distribution Hub:
Engineered for automotive, marine, and industrial applications, this 12V bus bar handles 300A continuous loads. Features 4 corrosion-resistant M6 studs for main battery lines and 12 M4 studs for accessories – ideal for car audio systems, winches, and marine thrusters requiring robust power management.

Marine-Grade Construction and Safety:
Nickel-plated brass busbar ensures maximum conductivity with minimal voltage drop. Glass-fiber reinforced nylon housing withstands salt spray, fuels, and extreme temperatures (-40°C to 125°C), while flame-retardant materials (UL 94V-0) prevent arc faults in demanding environments.

Modular Terminal Flexibility:
Dual bus bars with removable linking plates enable custom configurations. Removable access windows simplify wiring of 4-8 AWG cables, reducing installation time by 50% compared to traditional terminal blocks in complex systems.

High-Density Space Optimization:
Compact 138x69x44.5mm design integrates into tight engine compartments or electrical panels. Features blank labeling spaces for circuit identification and vibration-proof terminals to maintain connections in off-road/rough-water conditions.

Certified Marine and Automotive Compliance:
Exceeds ABYC E-11 and SAE J1128 standards with IP65-rated splash protection. Integrated insulating barriers prevent accidental shorts, while nickel-plated contacts resist electrolytic corrosion in saltwater applications.
