Frequently Asked Questions
Q: What is the amperage rating and wire gauge for the 317-1722-P connector?
A: The 317-1722-P is an SB350 series 2/0 gray connector rated for 350 amps. It accommodates 2/0 AWG wire and is designed for high-current battery distribution systems on heavy-duty electric lift trucks and forklifts. The gray color designates this as a standard power connector.
Q: Which equipment types use SB350 2/0 gray connectors?
A: SB350 2/0 gray connectors are installed on Crown, Toyota, Raymond, Yale, Hyster, and Jungheinrich electric lift trucks and pallet jacks with 24V, 36V, and 48V battery systems. These connectors are typically used for main battery disconnect, main contactor feed, and heavy-duty power distribution. Confirm your equipment model and voltage before ordering.
Q: Can you use a smaller gauge wire in an SB350 2/0 connector?
A: No. Do not substitute smaller wire gauge such as 4/0 or 1/0 in an SB350 2/0 connector. Undersized wire will not fill the contact cavity properly, creating loose connections, arcing, and potential burnout. Always match wire gauge exactly to the connector specification.
Q: What is the expected service life of SB350 2/0 gray connectors?
A: SB350 2/0 connectors typically provide 7 to 10 years of service life in standard warehouse and dock conditions. High-cycle disconnect and reconnect operations, exposure to vibration, cold storage environments, or moisture can reduce lifespan to 4 to 6 years. Replace connectors showing visible corrosion, pitting, or loose contacts.
Q: What is the voltage and current handling capacity?
A: SB350 2/0 gray connectors are rated for continuous current up to 350 amps and voltages from 24V to 72V DC. Peak current capability is typically 600 to 800 amps for brief durations such as motor startup. These connectors are not suitable for AC circuits or voltages exceeding rated DC specifications.
Q: Are there equivalent SB350 connectors in different wire gauge sizes?
A: Yes. Related SB350 connectors include 3/0 (317-1726-P) for even heavier current, and 4/0 versions for extreme-duty applications. Each wire gauge variant is a separate part number and must match your equipment wiring schematic and amperage requirements. Do not interchange different gauge SB350 connectors on the same circuit.
