DESCRIPTION
Victron 150A 4-Terminal Busbar for High-Current DC Distribution
Elevate your power management and streamline your electrical system with the Victron 150A 4-Terminal Busbar. Designed specifically for safe and efficient high-current distribution, this critical component acts as a central hub for connecting batteries, solar charge controllers, inverters, and other high-draw DC equipment. Whether you are upgrading a dual battery system in a caravan or building a comprehensive off-grid power plant, maintaining an organised electrical layout is essential for long-term safety and performance.
Engineered for Demanding Marine and Off-Grid Environments
A common issue with generic power distribution blocks is their susceptibility to corrosion and poor conductivity over time, which can lead to dangerous voltage drops or hot spots. Victron addresses these risks by utilising a highly conductive 1.4 x 18 mm tin-plated copper strip. The tin plating actively resists oxidation, making it highly suitable for harsh coastal or marine applications. Furthermore, the four 1/4 inch (6.35 mm) stainless steel terminal studs provide robust mechanical connections that can handle high torque (recommended 7 N·m) without stripping, ensuring excellent electrical contact for heavy-duty cable lugs.
Versatile Voltage Compatibility
While many enthusiasts look specifically for a 12V bus bar for their camper or automotive projects, this component is rated for a maximum DC voltage of 70V. This broad rating makes it exceptionally versatile and completely suitable for 24V and 48V marine and off-grid solar systems. When configuring your system, remember that the unit has a maximum current capacity of 150A (*Note typical de-rating factors apply depending on ambient temperature and continuous load duration).
Enhanced Safety and Professional Cable Management
Working with high-current DC systems requires strict attention to safety. Leaving cables stacked directly onto battery terminals not only looks messy but significantly increases the risk of short circuits and terminal stress. By routing your positive or negative connections through a dedicated 4 terminal bus bar, you reduce clutter and create a highly professional layout.
To further protect your installation, this busbar includes a clear polycarbonate cover (UL 94 HB rated) that shields the exposed studs from accidental contact with dropped tools or loose wiring. The entire assembly sits securely on a durable, black ABS base that features a UL 94 V-0 flame-retardant rating. Recessed, pre-drilled mounting holes allow for secure installation onto flat surfaces within your electrical enclosure, isolating the conductive elements away from metal chassis components.

WARRANTY
Victron Energy Limited Warranty Policy
Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the end user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead acid batteries; 2 years from date of purchase by the end user, with a maximum of 30 months from the Victron Energy invoice date, Lithium-ion batteries; 3 years from date of purchase by the end user. In addition to this proof of correct battery usage is required when making a battery warranty claim.
During this period, Victron Energy will, at its option, repair or replace the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation and re‐installation. This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use like: • Reverse of battery polarity. • Inadequate connection. • Mechanical shock or deformation. • Contact with liquid or oxidation by condensation. • Use in inappropriate environment (dust, corrosive vapor, humidity, high temperature, biological infestation...). • Breakage or damage due to lightning. • Connection terminals and screws destroyed or other damages, like overheat, due to insufficient tightening. • For any electronical breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state ofthe internal control diode and of the inputs/output X and Y capacitors determine the warranty.
This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone else than Victron Energy or one of its authorized Qualified Service Partners. In order to qualify for the warranty, the product must not be disassembled or modified.
