SB50 50A Power Connector Set

SB50 Connector Kit A complete 50 Amp SB50-style connector kit for building a durable, high-current quick-disconnect cable end. Ideal for batteries, chargers, DC-DC chargers, portable power boxes, HAM radio, marine gear, RVs, solar systems, and other DC power applications. Each kit includes one SB50 connector housing and two compatible contacts. Choose your housing colour and the contact size that matches your cable for a convenient, ready-to-assemble connector kit. One Complete Connector End Each kit includes one housing and two contacts — everything required to assemble one SB50 connector end. Most mated connections require two kits, with one connector installed on each cable. Shop Replacement Housings Shop Replacement Contacts Why You'll Love It Complete SB50-style connector kit with one housing and two contacts Rated for 50A continuous power connector applications Choose the contact size that matches your cable Colour-keyed housing helps prevent accidental cross-connection Silver-plated copper contacts provide a durable electrical connection Great for batteries, chargers, RVs, marine systems, HAM radio, solar, and portable power builds Colour-Keyed for Safer System Design SB50 housings are mechanically keyed by colour, meaning different colours are shaped differently and will not plug into each other. This makes it easier to separate different voltages, battery banks, charging circuits, or equipment types and helps prevent accidental misconnection. Suggested Uses Battery quick-disconnect connections Portable lithium power boxes and modular battery systems HAM radio and field power setups Quick-disconnects for trolling motors and small electric outboards DC-DC charger wiring in trailers, vans, campers, and service vehicles Diesel air heater power connections Auxiliary power feeds for fridges, camp lighting, and overlanding gear Clean disconnect points for chargers, solar gear, and DC equipment What’s Included 1 × SB50 Connector Housing (chosen colour) 2 × SB50 Contacts (chosen cable size) Need Both Sides of the Connection? This kit assembles one complete SB50 connector end. To create a full mated connection between two cables, order two kits of the same colour. The contact size can be different on each side if the cables are different sizes. Need Individual Replacement Parts? SB50 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 SB50 Housings Shop SB50 Contacts Frequently Asked What is included in this kit? Each kit includes one SB50 connector housing and two compatible contacts. Select the housing colour and contact size required for your cable. Does this kit make a complete connection? This kit makes one complete connector end. A typical connection between two cables requires two connector ends, so most installations will require two kits of the same colour. Do both connector ends need to be the same colour? Yes. SB50 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. The mating surface of compatible SB50 contacts is the same, 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 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. Properly matched contacts provide the best fit and crimp quality. If your cable size is not listed, separate SB50 contacts are available through the replacement contacts listing. Shop SB50 Contacts Are these connectors gendered? No. SB50-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 12V equipment, another for 24V equipment, and another for charging or accessory circuits. Because different colours do not mate together, this helps reduce the risk of connecting equipment to the wrong circuit. Will this fit other SB50-style connectors? These components are designed for SB50-style connector systems and are generally compatible with matching SB50-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 SB50 Housings Shop SB50 Contacts
