Victron Busbar 150A 4-Pole with Cover | VBB115040020

The Victron Energy 150A 4-pole busbar gives DC installations a single, rated connection point for splitting current across up to four circuits. Supplied with a protective cover, it suits battery banks, inverter installations and off-grid DC distribution boards where a tidy, secure connection is needed.

Key features

• Current rating, 150A continuous DC
• Poles, 4, allowing up to four separate circuit connections from one busbar
• Cover, protective cover included to guard against accidental contact and short circuits
• Weight, 0.17 kg
• GTIN, 8719076052197

Product overview

A busbar replaces multiple point-to-point cable runs with one rated connection rail. In this 4-pole layout, a single input from a battery or main fuse feeds up to four outputs, each wired independently, cutting down on terminals and wiring at the battery or inverter.

At 150A, it suits systems drawing significant continuous current, such as those built around Victron MultiPlus or Quattro inverter-chargers, or multi-battery setups. The cover isn't just cosmetic. It lowers the risk of accidental short circuits during installation and in service, which matters in any live DC panel. It's a small, functional part best mounted inside a suitable enclosure or distribution board rather than left exposed.

Applications

• DC distribution in off-grid solar systems with multiple load circuits
• Battery bank distribution in van, motorhome and marine installations
• Inverter and charger wiring consolidation in Victron system builds
• Distribution boards and enclosures needing a compact, rated busbar with a cover
• Commercial and industrial DC panel builds requiring circuit separation

What's in the box

Installation notes

Fit this busbar with a qualified electrician or experienced system integrator. Check the busbar is rated for the combined total current of all connected circuits, not just individual loads. Mount it within a suitable enclosure to keep the cover's protection intact, and isolate the battery or power source before making any connections. Work on grid-connected or solar PV systems should follow BS 7671 and any applicable G98 or G99 requirements.
