SB120 120A Power Connector Set

SB120 120A Power Connector Set A complete 120 Amp SB120-style power connector set for building a durable, high-current quick-disconnect cable end. Ideal for batteries, chargers, DC-DC chargers, portable power systems, RVs, marine equipment, solar installations, service vehicles, and other demanding DC power applications. Each set includes one SB120 connector housing and two compatible silver-plated contacts. Choose your housing colour and the contact size that matches your cable for a convenient, ready-to-assemble connector. One Complete Connector End Each set includes one housing and two contacts — everything required to assemble one SB120 connector end. Most mated connections require two sets, with one connector installed on each cable.

This makes it easier to separate different voltages, battery banks, charging circuits, or equipment types and helps prevent accidental misconnection. Suggested Uses High-current battery quick-disconnect connections Portable lithium battery banks and modular power systems Inverter and charger cable connections DC-DC charger wiring in RVs, trailers, vans, and service vehicles Marine battery and trolling motor connections Solar battery bank and off-grid power systems Commercial equipment and mobile power installations Clean disconnect points for high-current DC equipment What’s Included 1 × SB120 Connector Housing (chosen colour) 2 × SB120 Contacts (chosen cable size) Need Both Sides of the Connection? This set assembles one complete SB120 connector end. To create a full mated connection between two cables, order two sets of the same colour. The contact size can be different on each side if the connected cables use different wire sizes. Add a Pull Handle An optional SB120 pull handle can be bolted to the housing to provide a larger, more comfortable gripping point. This helps make frequent connection and disconnection easier while reducing the temptation to pull directly on the cables. Shop SB120 Pull Handle Need Individual Replacement Parts? SB120 housings and contacts are also available separately, making it easy to repair an existing connector, replace a damaged component, or build a custom combination. Shop SB120 Housings Shop SB120 Contacts Frequently Asked What is included in this set? Each set includes one SB120 connector housing and two compatible contacts. Select the housing colour and contact size required for your cable. Does this set make a complete connection? This set makes one complete connector end. A typical connection between two cables requires two connector ends, so most installations will require two sets of the same colour. Do both connector ends need to be the same colour? Yes. SB120 housings are mechanically keyed by colour. Only housings of the same colour and housing size are designed to mate together. Can I use different contact sizes on each side? Yes. Compatible SB120 contacts share the same mating interface even when the cable barrel is sized for a different wire gauge. This allows one side of the connection to use a different cable size than the other. Always size the circuit protection for the smallest conductor in the circuit. How do I choose the correct contact size? Select the contact size that matches the conductor size of your cable. A properly matched contact provides the best cable fit, crimp quality, and electrical connection. If you need a different size or additional contacts, they are available separately through the SB120 contacts listing. Shop SB120 Contacts Are these connectors gendered? No. SB120-style connectors use a genderless housing design. Two matching housings of the same size and colour connect directly to each other. Can I use different colours for different systems? Yes. This is one of the main advantages of colour-keyed housings. For example, you may use one colour for one battery voltage, another for charging equipment, and another for accessory or auxiliary circuits. Because different colours do not mate together, this helps reduce the risk of connecting equipment to the wrong circuit. Can a pull handle be added to this connector? Yes. A compatible SB120 pull handle can be bolted to the connector housing. The handle provides a larger gripping point, making the connector easier to separate without pulling directly on the cables. The handle is sold separately and does not need to match the colour of the connector housing. Connector colour keying applies to the housings, not the handle. Shop SB120 Pull Handle Will this fit other SB120-style connectors? These components are designed for SB120-style connector systems and are generally compatible with matching SB120-style components of the same colour and housing size. For the best fit, use matching components from the same product series. Can I buy the housing or contacts separately? Yes. Replacement housings and contacts are available separately for repairs, replacements, and custom connector combinations. Shop SB120 Housings Shop SB120 Contacts
