SB350 CONNECTOR SET

SB350 CONNECTOR SET

The SB350 CONNECTOR SET is a high-current, two-pole quick-disconnect connector system for battery, EV, UPS, inverter and industrial DC power connections. The SB350 form factor is widely used where large cable sizes and frequent connect/disconnect service are required. Buyers commonly search for SB350 battery connector, 350A connector set, high-current quick disconnect and EV battery connector.

Electrical performance is determined by the complete connector assembly: housing, contact size, conductor cross-section, crimp quality, mating force and temperature rise under load. Anderson's genuine SB350 family is a genderless two-pole system with contact options for very large conductors and published current capability that varies with wire size and certification method. A generic SB350-compatible set should not automatically be assigned the same UL or CSA ratings unless the supplied product carries that certification. Low contact resistance depends on clean contacts and a full, correctly crimped conductor barrel. High-current connectors can overheat quickly if a contact is under-crimped, partially inserted or used with cable that is too small for the load.

Match the connector by SB350 housing geometry, keying/colour, contact size, wire cross-section and operating current. Confirm whether the existing equipment uses a genuine Anderson housing or a compatible clone, because colour and keying can affect mating. Select cable and contact size together, then use the correct crimp tooling. Do not rely on the plastic housing name alone to set the circuit current; fuse and cable selection must still protect the wiring and battery.

For procurement and production use, compare the physical item with the approved sample before standardising the bill of materials. Check dimensions, connector or mounting geometry, supplied accessories and any markings that identify the exact variant. Where the application has a safety-critical electrical, thermal or mechanical requirement, use the manufacturer datasheet for the stocked part rather than a visually similar market product. Recording the approved item code and revision helps prevent a replacement part with the same generic name but different construction from entering the assembly process.

Applications

• High-current battery bank quick-disconnects.

• Electric vehicles, material-handling equipment and traction battery harnesses.

• UPS, inverter and energy-storage DC connections.

• Battery chargers, service cables and workshop test leads.

• Industrial DC equipment requiring a robust two-pole connector.

Installation Guide

Disconnect and isolate the battery before assembly. Strip the cable to the contact manufacturer's recommended length without cutting conductor strands, crimp with tooling intended for the selected contact, and inspect the finished crimp for full compression. Insert each contact until it is positively retained, verify polarity before mating, and provide cable strain relief. After initial operation, check the connector for abnormal heating, looseness or discoloration; any sign of heat damage requires the current path to be inspected and corrected.

Why Choose ARB Accessories?

ARB Accessories focuses on lithium-battery, EV, energy-storage and battery-pack assembly components. The catalog brings together BMS boards, connectors, insulation materials, battery wiring, terminals, fuses, enclosures, testing equipment and assembly tools. For battery builders, repair workshops and OEM buyers, sourcing related components from one specialist catalog can make specification matching and procurement easier. Final suitability should still be checked against the exact battery design, equipment model and electrical requirements before installation.
