Frequently Asked Questions
Q: What are the electrical specifications for the 300073-000 contactor?
A: The 300073-000 is a 24VDC nominal coil voltage contactor rated for 100A continuous current at 24VDC. It is designed for traction and lift circuit switching in electric lift trucks. The contactor features copper alloy contacts, a phenolic resin base, and stud terminals with 0.625 inch tip diameter.
Q: Which lift truck brands and models does the 300073-000 contactor fit?
A: This contactor is compatible with select BT and Prime Mover electric lift truck models. The OEM part number is 300073-000, and it is also referenced as BT300073-000. Verify your equipment manufacturer and model year before ordering to confirm compatibility.
Q: What is the mechanical and electrical life expectancy of this contactor?
A: The 300073-000 contactor has a rated mechanical life of up to 500,000 cycles at rated load and an electrical life of 100,000 cycles at full rated load. Actual lifespan depends on load conditions, voltage stability, and duty cycle in your lift truck application.
Q: How do I know if the 300073-000 contactor needs replacement?
A: Replace the contactor if the lift truck experiences intermittent power loss, clicking relay sounds without motor engagement, traction circuit failures, or burning odors from the electrical housing. Burned or pitted contacts are a clear indication of failure. A meter test showing no continuity between coil and main terminals confirms failure.
Q: What maintenance does the 300073-000 contactor require?
A: Inspect the contactor periodically for corrosion on stud terminals and housing. Ensure proper 24VDC supply voltage at the coil. Clean terminal connections to prevent voltage drops. No adjustments are required; contactors are sealed and non-serviceable.
