Description Sturdy - The base of the busbar is made of nylon, which is heat-resistant . In addition, stainless steel stud terminals are corrosion-resistant, and nickel-plated copper plates also endow Marine busbars with high electrical conductivity and superior corrosion resistance, effectively extending the service life of the busbars. 1/4 "stud terminal - Battery busbar terminal and 5 × 1/4" (M6) stud terminal, which enables the 12V busbar to accept terminal connectors and wire installations of various sizes. Moreover, the nut designed with the washer also makes the contact between the nut, the wire lugs and the terminal housing tighter, easier to tighten and safer to use. Rated and sized - Maximum current: 150A D.C, 130A AC. Maximum voltage: 48V D.C, 300V AC. The overall dimensions of this small busbar are 4.2 inches x 0.9 inches x 1.1 inches. Wide application range - The 12V distribution block with a cover helps protect more exposed areas and prevent accidental short circuits. Of course, the busbar helps to keep the wiring neat and prevent electrical short circuits caused by messy wire harnesses. Battery bus ducts can be widely applied in automobiles, sedans, trucks, recreational vehicles, motorcycles, ships, small boats, steamships, etc. The packaging includes: 1/2*Automotive terminal block
