Frequently Asked Questions
Q: What CAT lift truck models are compatible with the CTR-24-289?
A: The CTR-24-289 is compatible with CAT electric lift truck models including PE4500, WP2000, WP2300, WP3000, and WP3035-45. Verify your equipment model and serial range before ordering. If you are uncertain whether your truck is within the compatible range, check your truck nameplate or equipment documentation.
Q: What are the main electrical specifications of the CTR-24-289?
A: The CTR-24-289 features a 24VDC coil voltage with an 80-ampere contact rating. It is rated for intermittent duty operation with single pole, single throw copper alloy contacts. The contactor is designed for power circuit switching in electric lift truck control systems.
Q: What cross-reference and equivalent part numbers apply to the CTR-24-289?
A: The CTR-24-289 replaces part number 154548, supersedes 800076344, and is equivalent to 802820, CT544-24, SW80-1005L, SW80-113L, and SW80-740L. When ordering, use the OEM CAT part number CTR-24-289 to ensure correct fitment on your equipment model.
Q: What contact materials does the CTR-24-289 use?
A: The CTR-24-289 uses single pole, single throw copper alloy contacts rated at 80 amperes. Copper alloy contacts provide reliable electrical conductivity and performance in high-current switching applications typical of electric lift truck power circuits.
Q: Is the CTR-24-289 rated for continuous or intermittent duty?
A: The CTR-24-289 is rated for intermittent duty operation. The coil should be cycled on and off rather than held in a continuously energized state. Continuous energization can cause overheating and damage. If your application requires continuous coil duty, contact us to discuss alternative contactor options.
