SB350 350A Power Connector Set

SB350 350A Power Connector Set A complete 350 Amp SB350-style power connector set for building a durable, high-current quick-disconnect cable end. Ideal for large battery banks, inverters, industrial chargers, commercial vehicles, heavy equipment, marine systems, off-grid power installations, and other demanding DC power applications. Each set includes one SB350 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 SB350 connector end. Most mated connections require two sets, with one connector installed on each cable. Shop Replacement Housings Shop Replacement Contacts Why You'll Love It Complete SB350-style connector set with one housing and two contacts Rated for 350A continuous power connector applications Available with contacts for multiple large cable sizes Colour-keyed housing helps prevent accidental cross-connection Silver-plated copper contacts provide a durable, low-resistance connection Optional pull handle can be added for easier connection and disconnection Colour-Keyed for Safer System Design SB350 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 Large battery-bank quick-disconnect connections High-capacity lithium battery and energy-storage systems Large inverter and inverter-charger cable connections Industrial battery chargers and power equipment Commercial vehicles, forklifts, and heavy mobile equipment Marine battery banks and electric propulsion systems Solar battery banks and off-grid power installations High-current disconnect points for demanding DC equipment What’s Included 1 × SB350 Connector Housing (chosen colour) 2 × SB350 Contacts (chosen cable size) Need Both Sides of the Connection? This set assembles one complete SB350 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 pull handle can be bolted to the SB350 housing to provide a larger, more comfortable gripping point. This makes frequent connection and disconnection easier while reducing the temptation to pull directly on the cables. Shop SB175 / SB350 Pull Handle Need Individual Replacement Parts? SB350 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 SB350 Housings Shop SB350 Contacts Frequently Asked What is included in this set? Each set includes one SB350 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. SB350 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 SB350 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. Available contact sizes include 2 AWG, 1/0 AWG, and 2/0 AWG. Additional or replacement contacts are also available separately. Shop SB350 Contacts Are these connectors gendered? No. SB350-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 separate battery banks or equipment 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 SB175 / SB350 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 SB175 / SB350 Pull Handle Will this fit other SB350-style connectors? These components are designed for SB350-style connector systems and are generally compatible with matching SB350-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 SB350 Housings Shop SB350 Contacts
