SB350 Connector Housing
A durable SB350-style connector housing for building or repairing very high-current quick-disconnect power connections. Ideal for large battery banks, high-power inverters, industrial equipment, forklifts, marine systems, service vehicles, and demanding off-grid DC power systems.
This listing is for ONE (1) SB350 connector housing only. Compatible SB350 contacts are sold separately, allowing you to choose the correct contact size for your cable and application.
Housing Only
This product includes one SB350 connector housing only. Contacts, handles, and complete connector kits are sold separately.
Why You'll Love It
- Replacement SB350-style connector housing
- Sold individually — one housing per unit
- Rated for 350A continuous power connector applications
- Colour-keyed housing helps prevent accidental cross-connection
- Use with compatible SB350 contacts in the wire size you need
- Ideal for large battery banks, high-power inverters, industrial equipment, marine, and off-grid power systems
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 is useful when separating different voltages, battery banks, charging circuits, or equipment types — helping prevent accidental misconnection between systems.
Suggested Uses
- Large battery bank quick-disconnect connections
- High-power inverter and charger connections
- Industrial and forklift battery systems
- Large off-grid lithium power systems
- Marine and commercial vehicle electrical systems
- Service vehicle and utility equipment wiring
- Heavy-duty DC power distribution

Need a Complete Connector?
This product includes one SB350 connector housing only. If you're building a complete connector, you'll also need compatible SB350 contacts sized for your cable.
Frequently Asked
Is this a complete connector?
No. This product includes one SB350 connector housing only. To build a complete connector, you will also need compatible SB350 contacts.
Are contacts included?
No. This listing is for the SB350 housing only. Contacts are sold separately so you can choose the correct contact size for your cable.
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. SB350 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 SB350 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 SB350-style connectors?
These housings are designed for SB350-style connector systems and are generally compatible with matching SB350-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 SB350 connector end, you need one housing and two compatible SB350 contacts. To make a full mated connection between two cables, most installs require two housings and four contacts.
