Frequently Asked Questions
Q: What are the voltage specifications for the YL 504908502 contactor?
A: The YL 504908502 is rated for 36VDC to 48VDC nominal coil voltage and control voltage. This contactor is designed for mid-to-high voltage electric lift truck systems, specifically Yale models operating on 36 or 48-volt direct current power supplies.
Q: How do the contact materials differ in the YL 504908502 compared to lower-voltage contactors?
A: The YL 504908502 uses copper alloy contacts instead of silver alloy. Copper alloy contacts are suitable for the higher voltage and different switching profiles in 36/48-volt systems. The molded thermoset body provides improved insulation and thermal management appropriate for higher-voltage applications.
Q: What cross-reference part numbers are equivalent to YL 504908502?
A: The YL 504908502 is interchangeable with YT504908502, YT 504908502, and YL504908502. These markings identify the same OEM Yale panel-mount contactor. Always verify the voltage marking on your truck before substituting parts.
Q: Why is the YL 504908502 mounted on a panel versus other mounting styles?
A: Panel-mount design allows the YL 504908502 to be installed directly on the truck control module or power distribution panel, consolidating wiring and reducing component scatter. Stud terminals provide secure mechanical and electrical connection to panel-mounted bus bars or terminal blocks.
Q: Which Yale lift truck models use the YL 504908502?
A: The YL 504908502 is compatible with select Yale electric lift truck models rated for 36 or 48-volt systems. Verify your truck model, serial number, and system voltage match this specification. Contact us with your equipment details to confirm exact compatibility.
