48 V DC Bus Bar — 250 A continuous, red (positive) and black (negative) terminals Key benefits Reliable power distribution for DC systems: centralizes positive and negative connections to reduce wiring complexity and voltage drops. High continuous current capacity: supports heavy loads and multiple branch circuits without overheating. Durable, safe construction: corrosion-resistant metals and a robust insulating cover protect connections and reduce short-circuit risk. Easy, secure installation: bolt terminals provide firm, low-resistance connections for ring terminals and cable lugs. Main features Voltage and current ratings: rated up to 48 V DC with a continuous current capacity up to 250 A. Each terminal can handle up to 250 A at 12 V DC. Color-coded terminals: red (positive) and black (ground/negative) for clear, error-free wiring. Bolt connections: equipped with two stainless steel bolts for each terminal to ensure secure, vibration-resistant joins. Material and build: high-strength nickel-plated brass bus plate for low resistance and corrosion resistance. Protective cover: tough polycarbonate plastic cover provides impact resistance and short-circuit protection while allowing visual inspection. Compatibility and performance Designed for DC power distribution in 12 V to 48 V systems. Suitable for use with standard ring lugs, cable lugs and spade connectors compatible with the provided bolt size. Handles continuous heavy current demands while maintaining stable contact and low thermal rise. Safety and maintenance Nickel-plated brass resists corrosion; stainless steel bolts resist loosening in vibration environments. Polycarbonate cover reduces accidental contact and helps prevent shorts; remove cover only when making or inspecting connections. Periodic inspection of bolt torque and corrosion-free contacts keeps performance reliable. Typical applications Marine and boating electrical panels: distribute battery and charger outputs to multiple circuits with corrosion-resistant materials. RV and camper power systems: central junction for battery banks, inverters, chargers and DC accessories. Off-grid solar and battery systems: organize positive and negative outputs from battery banks, charge controllers and inverters for safer, cleaner wiring. What this solves Eliminates messy, high-resistance multi-splice connections by providing a single, low-resistance distribution point. Reduces risk of loose or corroded connections that cause voltage drops, heat buildup or intermittent faults. Simplifies system expansion and troubleshooting by grouping DC distribution on clearly labeled terminals.
