Frequently Asked Questions
Q: What is the rated current and voltage for the CT 973793 fuse?
A: The CT 973793 is rated for 175 amps at 32 VDC or 125 VAC. It is designed specifically for electric lift truck charging alternator circuits and provides protection at both DC and AC voltages.
Q: What are the physical specifications and mounting type?
A: This fuse features a 68 mm copper body with a visible link design and bolt-down mounting configuration. The copper construction provides excellent conductivity and heat dissipation in charging circuits.
Q: Does the CT 973793 fit Caterpillar electric forklifts?
A: Yes. The CT 973793 is an OEM Caterpillar part (973793, 0973793). Cross-reference part number 239-8107 also identifies this fuse. Verify your equipment model matches charging alternator circuit requirements before ordering.
Q: What does visible link fuse design mean?
A: A visible link fuse allows direct inspection of the internal fusible element without disassembly. If the fuse has operated, the open link is visible through the transparent or translucent body, providing instant confirmation that the fuse has blown.
Q: Why is copper used in the body construction?
A: Copper body construction is selected for high-current charging alternator circuits because copper provides superior thermal conductivity and electrical conductivity. This reduces resistive heating and allows the fuse to handle 175 amps reliably in lift truck charging systems.
