Frequently Asked Questions
Q: What is the CT A00005939 Fuse 500A used for?
A: The CT A00005939 is a 500-amp fuse designed for electric lift trucks and material handling equipment. This fuse protects the main electrical circuit from overcurrent conditions and short circuits in heavy-duty industrial applications.
Q: Which electric lift truck models use the CT A00005939 Fuse 500A?
A: The CT A00005939 is compatible with Caterpillar electric lift trucks and forklifts that require a 500-amp main circuit fuse. Verify your equipment specifications before ordering. Check your truck nameplate or electrical schematic to confirm the correct amperage rating for your model.
Q: How do I know if the CT A00005939 fuse has failed?
A: Symptoms of a blown 500A fuse include loss of power to the truck, no response when turning on the ignition, or intermittent electrical failures. If the truck loses power completely, inspect the main fuse first. A blown fuse will show a broken element or blackened interior when examined visually.
Q: What voltage rating does the CT A00005939 Fuse 500A operate at?
A: The CT A00005939 is rated for the electrical system voltage of Caterpillar electric lift trucks, typically 12V, 24V, or 36V DC depending on the truck model. Verify the correct voltage for your equipment before ordering to prevent electrical damage.
Q: How often should the CT A00005939 Fuse 500A be replaced?
A: Fuses should not need replacement under normal operating conditions. Replace only when blown or failed. If fuses blow repeatedly, the underlying electrical fault must be diagnosed and corrected to prevent continued fuse failures and equipment downtime.
