Product Description
CONTACTOR (24 VOLT)
Frequently Asked Questions
Q: What function does the CT994-24 contactor serve?
A: The CT994-24 is a 24-volt DC electromagnetic control relay that switches power distribution circuits in electric lift truck systems. It controls high-current paths for motor drive, hydraulic pump circuits, and auxiliary loads under control system direction.
Q: What electric lift truck brands are compatible with CT994-24?
A: The CT994-24 is compatible with electric lift trucks and pallet jacks from manufacturers including Crown, Toyota, Raymond, Yale, Hyster, and similar OEMs. Cross-reference your equipment serial number and model year to confirm fitment.
Q: What is the electrical specification for CT994-24?
A: The CT994-24 operates at 24 VDC nominal coil voltage. The contactor is sized for typical lift truck switching loads, typically 200 to 350 amperes. Terminal configuration and mounting style are standardized for interchangeability across multiple OEM platforms.
Q: How do I determine if CT994-24 is the correct replacement?
A: Locate your truck model and serial number in the operator or service documentation. Cross-reference the contactor part number listed for your electrical system. Verify coil voltage, terminal count, and physical dimensions match. If specifications are unclear, provide your truck details for confirmation.
Q: What are failure symptoms for a CT994-24?
A: Common failure indicators include electrical dropout when under load, inability to energize circuits despite control inputs, humming or buzzing sounds, visible terminal corrosion, or internal contact arcing. Any sudden loss of drive or steering function suggests contactor failure.
Q: What preventive maintenance extends contactor life?
A: Maintain a stable 24-volt power supply without voltage sags or spikes. Keep the electrical compartment dry and free from moisture. Inspect terminals and contacts regularly for corrosion or white oxidation. Address any charging system faults or battery problems immediately, as electrical instability degrades contactors rapidly.
