Frequently Asked Questions
Q: What is contact set 516490802 and how is it used?
A: Contact set 516490802 is an electrical switching component for SB350 electric lift trucks with 3/0 cable specification. These contacts handle motor control and power distribution for the trucks traction system. The SB350 designation identifies the charger or electrical power management system.
Q: Which electric lift trucks are compatible with 516490802?
A: Contact set 516490802 fits SB350-equipped electric lift trucks from manufacturers including Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. The 3/0 cable gauge rating indicates this set is for higher-amperage power applications. Verify your specific truck model and electrical system before ordering.
Q: What does 3/0 cable specification mean on this contact set?
A: The 3/0 designation refers to 3/0 AWG (American Wire Gauge) and indicates the contact set is rated for higher amperage electrical loads compared to 2/0 components. The contacts and internal components are designed to safely handle the increased current flow in 3/0 cable systems. Never substitute a 2/0 set, as it cannot handle the amperage.
Q: How does 516490802 differ from 516490801?
A: Part 516490802 is designed for 3/0 cable and higher amperage applications, while 516490801 is designed for 2/0 cable and lower amperage. The two sets are not interchangeable. Each contact set has internal contact configurations and current ratings matched to its specific cable gauge requirement.
Q: What maintenance does a contact set require?
A: Contact sets do not require routine maintenance. However, inspect the connectors periodically for corrosion, pitting, or burn marks. If you notice arcing sounds, intermittent power delivery, or visible damage to the contact surfaces, the set should be replaced. Keep connector areas dry and free from debris.
Q: What happens if contact set 516490802 fails?
A: A failed contact set causes loss of electrical connection between the battery and traction motor, resulting in no power to the truck. You will experience complete loss of drive function and must replace the contact set to restore operation. Continuing to operate with a failed contact set risks further electrical system damage.
