Frequently Asked Questions
Q: What does the 317-1051 contact set do?
A: The 317-1051 is a contact set for the SB50A controller used in electric lift trucks. It manages electrical connections in the main contactor assembly, enabling power delivery to motors and lift circuits.
Q: What electric lift truck models use the 317-1051 contact set?
A: This contact set is designed for electric pallet jacks and lift trucks equipped with SB50A controllers. Verify your truck model and control system before ordering to ensure compatibility.
Q: What is the function of the number 6 designation in the 317-1051?
A: The number 6 refers to the specific pole or terminal configuration within the SB50A contact assembly. Different numbers indicate different electrical configurations for varied load and amperage requirements.
Q: How do I know when the 317-1051 contact set needs replacement?
A: Replace contacts if lift power cycles erratically, if the truck is intermittently unresponsive, or if visual inspection reveals pitting or burning on contact surfaces. Electrical testing will confirm contact wear.
Q: Is the 317-1051 a wear part?
A: Yes. Electrical contacts degrade through repeated switching cycles and electrical arcing. Lifespan depends on usage hours and amperage load. High-duty trucks require more frequent replacement than light-duty units.
