CONTACT SET (SB350 3/0)
Frequently Asked Questions
Q: What is the 800049839 contact set used for in electric lift trucks?
A: The 800049839 is a contact set for the SB350 connector series rated at 3/0 (3 zero gauge, approximately 85 mm squared). This contact set is designed for high-current power distribution in electric lift truck battery charging and traction motor circuits. It is compatible with Crown, Toyota, Raymond, Yale, Hyster, and other OEM electric material-handling equipment.
Q: What gauge wire does the 800049839 3/0 contact set accommodate?
A: The 800049839 is rated for 3/0 gauge (3 zero AWG) wire, which measures approximately 85 mm squared in cross-sectional area. This gauge is typical for high-current battery and traction motor leads in industrial electric lift trucks. Do not use this contact set with smaller gauge wire, as it will not achieve proper contact pressure and may cause arcing or intermittent connections.
Q: How does the 800049839 contact set maintain electrical continuity in high-current applications?
A: The 800049839 contact set features precision-engineered terminals with high surface-area mating surfaces designed to minimize resistance and maintain low contact impedance under sustained high-current load. The 3/0 gauge rating ensures sufficient cross-sectional area and material mass to conduct charging and motor currents without excessive heating or voltage drop.
Q: What material composition gives the 800049839 contact set durability?
A: The 800049839 contact set terminals are typically composed of copper or copper-alloy materials with plating or oxidation-resistant finishes. These materials provide excellent electrical conductivity, thermal management during high-current cycles, and resistance to corrosion from moisture and environmental contamination in storage and warehouse settings.
Q: How long is the service life of the 800049839 contact set?
A: The 800049839 contact set has a typical service life of 5-8 years under normal charging and motor duty cycles. Lifespan is reduced if contact faces become pitted, corroded, or blackened from arc damage, or if the mating surfaces develop loose fit or intermittent resistance. Regular inspection during maintenance ensures early detection of terminal degradation.
Q: Is there a cross-reference part number for the 800049839 contact set?
A: The 800049839 is a 3/0 gauge SB350-series contact set. Related components in the SB350 family include terminal housings SKU 800049833, 800049835, and 800049837. For OEM cross-reference information or if you need a different gauge or connector series, contact us with your equipment specifications.
