Frequently Asked Questions
Q: What are the electrical ratings and configuration of the 800064639 contactor?
A: The 800064639 is a 24VDC double pole contactor rated for 30A resistive load at 240VAC. Coil voltage is 24VDC nominal with ±10 percent tolerance. Inductive current rating is 30A FLA at 240VAC. The contactor features an open frame, panel mount design suitable for compact installation in lift truck control cabinets.
Q: What is the difference between the 30A resistive and inductive current ratings on the 800064639?
A: Resistive rating (30A at 240VAC) applies to purely resistive loads like heating elements. Inductive rating (30A FLA) applies to motor and pump loads that draw higher inrush current at startup. The locked rotor amps (LRA) for the 800064639 are 180A at 240VAC, 150A at 480VAC, and 120A at 600VAC. Never exceed the inductive rating for motor applications.
Q: Which electric lift truck applications is the 800064639 designed for?
A: The 800064639 is suitable for 24VDC electric lift truck circuits where compact, durable switching of moderate-current loads is required. It is compatible with Crown, Toyota, Raymond, Yale, Hyster, and other major OEM brands. Typical applications include drive circuits, lift pump circuits, and auxiliary control circuits in 24VDC systems. Verify your equipment voltage and amperage match before ordering.
Q: Why is the 800064639 rated for 50/60 Hz operation?
A: The 50/60 Hz frequency rating refers to the alternating current (AC) frequency of the load circuit connections. North American equipment typically operates at 60 Hz. Some international lift trucks use 50 Hz power. The coil itself operates on 24VDC (direct current), so frequency rating applies only to AC loads connected through the 800064639 contacts.
Q: What does the open frame, panel mount design of the 800064639 mean for installation?
A: Open frame design means the contactor has an exposed coil and contacts with no protective enclosure. Panel mount indicates it is designed to be mounted directly to a control panel or electrical cabinet using bolt-down feet or bracket holes. The 800064639 fits compact spaces typical of lift truck control boxes where space is limited and cooling air must circulate freely around the coil.
Q: What is the service life of the 800064639, and how do I know when replacement is necessary?
A: The 800064639 typically lasts 5 to 7 years in normal lift truck service with moderate switching frequency. Replace the contactor if contacts become pitted or burned, if the coil fails to energize at 24VDC, if the contactor chatters or vibrates excessively during operation, or if it fails to hold a load. Open frame design makes contact inspection straightforward; replace if contacts appear black or welded together.
