Heavy Duty: Power distribution block can deal with 275 Amp continuous amperage at Max 300V AC or 48V DC voltage Durable: The tinned copper plate makes the marine bus bar have high conductivity and corrosion resistance performance, effectively extending the life of the bus bar Unique Design: The special fixing method of marine bus bar and base can withstand large torque, and the copper bar and base will not be easily separated Protect Cover: The heavy duty busbar cover can cover exposed areas to prevent accidental short circuits. The exposed areas on both sides allow multi-angle installations, which can meet various connection methods Wide Application: Using a pair of black and red bus bar terminal blocks for wire management and wiring can keep the circuit neat and orderly, reducing the possibility of short circuits.
