Victron Energy Busbar with Cover, 600A, 3/8 in and M8 Terminals

Overview

The Victron Energy Busbar 600 A with Cover is a covered DC busbar for high-current distribution in battery banks and DC equipment circuits. It is rated for a maximum current of 600 A and a maximum voltage of 70 VDC, making it a practical fit for larger low-voltage marine DC systems where battery, inverter, charger, alternator, and DC load connections need a clean common point.

The busbar uses a tin-plated copper conductor with stainless steel terminals, nuts, and screws. The removable ABS cover helps protect the connection area after installation, which is useful in battery compartments, technical lockers, and other service areas where covered high-current connections are preferred.

Key features

• 600 A maximum current rating for high-current DC distribution on boats and off-grid power systems.
• 70 VDC maximum voltage rating for low-voltage DC battery and equipment circuits.
• 3/8 inch / 9.53 mm main terminal diameter for high-current cable connections.
• Includes low-current screw terminals with #8 / 4.2 mm diameter screws for auxiliary connections.
• Tin-plated copper busbar with stainless steel terminals, flange nuts, and screws.
• Black ABS base with UL 94 V-0 rating and black ABS cover with UL 94 V-2 rating.
• Recommended torque is 20 N-m for the main terminals and 2 N-m for the screw terminals.
• Available in 4P and 8P versions, depending on the number of high-current connection points needed.

Variants

This busbar is offered in two configurations with the same 600 A current rating and removable cover. The main difference is the number of high-current connection points.

Both versions use 3/8 inch / 9.53 mm main terminals and include 8 low-current screw terminals. The 4P version has a shorter body, while the 8P version gives more high-current connection points for larger DC layouts.

• VBB160040010: Current rating 600 A, connections 4P. This version suits DC layouts that need fewer high-current take-offs while still keeping battery and equipment connections on a covered busbar.
• VBB160080010: Current rating 600 A, connections 8P. This version gives more high-current connection points for systems with several large DC cables feeding batteries, inverters, chargers, or distribution equipment.

Installation and fit

Plan the mounting location so the cover can be removed for inspection and the cable lugs can be tightened without strain on the terminals. The 4-terminal version measures 65 x 216 x 86 mm with the cover fitted and weighs about 0.75 kg. The 8-terminal version measures 65 x 327 x 86 mm with the cover fitted and weighs about 1.3 kg.

Use properly sized DC cable, correctly crimped lugs, and suitable overcurrent protection for the circuit. The recommended torque values matter on a boat because vibration and cable movement can loosen poor connections over time.

Use on board

This busbar is a good match for marine electrical upgrades where several heavy DC cables need to land at one organized point rather than stacking cables on battery posts. It is commonly used in battery compartments, inverter and charger installations, and service areas where a covered distribution point makes the system easier to inspect and maintain.

Because it is a non-fused busbar, circuit protection still needs to be handled elsewhere in the system. Install it as part of a complete DC layout that accounts for cable size, fuse or breaker placement, battery isolation, and access for routine checks.

Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
