This is useful when separating different voltages, battery banks, charging circuits, or equipment types — helping prevent accidental misconnection between systems. Suggested Uses Battery bank quick-disconnect connections High-current inverter and charger connections Off-grid lithium battery systems Solar power systems and charging equipment Marine electrical systems RV and service vehicle power distribution Winches, utility equipment, and commercial vehicle wiring Specifications Connector Series SB175 Continuous Current Rating 175 Amps Housing Material High-Impact Polycarbonate Compatible Contact Sizes 6 AWG, 4 AWG, 2 AWG, 1/0 AWG Housing Compatibility SB175 Contacts What’s Included 1 × SB175 Connector Housing (chosen colour) Need a Complete Connector? This product includes one SB175 connector housing only. If you're building a complete connector, you'll also need compatible SB175 contacts sized for your cable. Shop Complete Connector Kits Shop SB175 Contacts Frequently Asked Is this a complete connector? No. This product includes one SB175 connector housing only. To build a complete connector, you will also need compatible SB175 contacts. Shop Complete Connector Kits Are contacts included? No. This listing is for the SB175 housing only. Contacts are sold separately so you can choose the correct contact size for your cable. Shop SB175 Contacts Shop Complete Connector Kits How many housings do I need for one connection? Most installations require two housings — one on each cable being connected. This listing includes one housing, so order two housings if you need both sides of a connection. Do different colours connect together? No. SB175 housings are mechanically keyed by colour. Different colours are shaped differently and are designed to only mate with the same colour and same housing size. This can be useful for separating different voltages, battery banks, chargers, or equipment types so they cannot be accidentally plugged into the wrong system. Can I use different colours for different systems? Yes. That is one of the main advantages of colour-keyed housings. For example, you may choose one colour for 12V equipment, another for 24V equipment, and another for charging or accessory circuits. Since different colours do not mate together, this helps reduce the risk of accidental cross-connection. Can I use different contact sizes or wire gauges? Yes. You can use different compatible SB175 contact sizes on either side of the connection. The mating surface of the contact is the same, while the crimp barrel is sized for the cable being used. This can be useful when transitioning between different wire sizes, such as a larger cable on a long run and a smaller cable near the device. Important: Always fuse the circuit for the lowest-rated conductor or component in the system. Will this fit other SB175-style connectors? These housings are designed for SB175-style connector systems and are generally compatible with matching SB175-style components of the same colour and housing size. For best results, use matching housings and contacts from the same product series. What else do I need to build a complete connector? To build one complete SB175 connector end, you need one housing and two compatible SB175 contacts. To make a full mated connection between two cables, most installs require two housings and four contacts. Shop SB175 Contacts Shop Complete Connector Kits
