Bus Bar 12V 250A 4M10+6M4 Studs Marine Battery Automotive Boat

Description:

Heavy-Duty 250A Power Distribution Hub:
Engineered for automotive, marine, and industrial systems, this 12V bus bar handles 250A continuous loads. Centralizes connections for batteries, alternators, and accessories using 4 corrosion-resistant M10 studs (main lines) and 6 M4 studs (accessories) - ideal for car audio, winches, or solar arrays.

Marine-Grade Copper Core and 304SS Contacts:
Oxygen-free copper busbar ensures minimal voltage drop at peak loads. 304 stainless steel terminals resist saltwater corrosion and electrolysis, maintaining stable connections in engine bays or bilge areas (-30°C to 105°C operating range).

Reinforced PC-Nylon Housing and Safety Cover:
Impact-resistant polycarbonate shell with nylon base withstands fuels, oils, and vibrations. Optional snap-on cover provides IP65 splash protection while allowing visual inspection of connections in high-density electrical panels.

1-5 AWG Universal Compatibility:
Accommodates 1-5 AWG wires across all 10 terminals. Color-coded labels and flared entry ports prevent strand damage during installation - reducing setup time by 40% versus individual lugs in complex systems.

Short-Circuit Prevention and Compliance:
Flame-retardant materials (UL 94V-0) suppress arc faults. Exceeds SAE J1128 and ABYC E-11 standards with integrated insulating barriers between terminals, preventing accidental contact in marine/automotive applications.
