Connector (sb350 3/0 gray)
Frequently Asked Questions
Q: What wire gauge and current rating does the SB350 3/0 gray connector handle?
A: The 317-1726-P is an SB350 series 3/0 gray connector rated for 350 amps continuous current with 3/0 AWG wire. This connector is used in maximum-current battery distribution paths on heavy-duty electric forklifts and lift trucks, typically for direct battery-to-main-contactor connections. The gray color indicates standard power circuit duty.
Q: What equipment models and OEM brands use SB350 3/0 connectors?
A: SB350 3/0 gray connectors are found on premium and heavy-duty models from Crown, Toyota, Raymond, Yale, Hyster, Linde, and Jungheinrich electric lift trucks rated 48V and above. These connectors typically connect the main battery terminals directly to the motor contactor or main power distribution block. Verify your specific model and serial range for compatibility.
Q: Is 3/0 wire different from 2/0 in the same SB350 connector family?
A: Yes. 3/0 AWG is larger in diameter than 2/0 AWG and carries higher continuous current capacity. SB350 3/0 (317-1726-P) and SB350 2/0 (317-1722-P) are different parts with different contact cavities sized for their respective wire gauges. They are not interchangeable even though they share the same SB350 series name.
Q: How long do SB350 3/0 connectors typically last in cold storage environments?
A: In cold storage and frozen food warehouse duty, SB350 3/0 connectors typically last 5 to 7 years due to accelerated corrosion from condensation and temperature cycling. Regular visual inspection every 6 months is recommended. Replace immediately if oxidation appears on contacts or if you observe increased resistance during battery load tests.
Q: What are the physical dimensions and connector body material?
A: SB350 series connectors use a composite plastic body with silver-plated copper contact surfaces. The 3/0 variant is physically larger than 2/0 to accommodate the thicker wire gauge. Contact surfaces are typically 0.375 inches to 0.5 inches in diameter to handle 350-amp continuous current without excessive heat generation.
Q: Can I use an SB350 3/0 connector instead of 2/0 if I have oversized wire available?
A: Only if your equipment schematic and OEM wiring diagram specify 3/0 as the correct connector type for that circuit. Do not upgrade connector sizes beyond OEM specification. Oversized connectors may not mate properly with corresponding male connectors, creating gaps, arcing, and potential equipment damage.
