Heavy duty power distribution block for high current 12V systems - Heavy duty capacity: 250 Amp continuous at up to 300V AC or 48V DC, providing a robust distribution point for high-current circuits. - Dual-row bus bar: 12V bus bar in red and black, with each row containing 6 x 5/16” stainless steel studs for reliable connections and clear polarity. - Durable marine-grade design: The copper bus bar is fixed to a marine-grade base with a special fixing method that withstands large torque, so the copper bar and base stay firmly joined and resist separation. - Protective cover and installation flexibility: A heavy duty cover shields exposed areas to prevent accidental shorts, while the exposed sides allow 180° installations to accommodate various wiring configurations. - Practical applications: Ideal for marine electrical systems (power distribution for pumps, lights, and accessories), RV or off-grid solar/battery setups, and automotive workshop or heavy equipment power distribution. - Key features at a glance: high current capacity, dual-row 12V layout, red/black polarity, stainless steel studs, copper bar with secure fixed base, and comprehensive protection with versatile 180° installation options.
