Frequently Asked Questions
Q: What are the electrical specifications of the CT 973045 200-amp fuse?
A: The CT 973045 is a 200-amp high-current bolt-on fuse rated for up to 125VDC. It features a thermoset molded base and is designed for heavy-current protection in electric lift truck power circuits. Cross-reference numbers include 113-8490, ACK SK-55240130JE.
Q: Which Caterpillar electric lift truck models use the CT 973045 200-amp fuse?
A: The CT 973045 protects primary power circuits on Caterpillar electric lift trucks requiring 200-amp main fuse protection. Confirm your equipment model and serial number. Equivalent numbers 0973045, 973045, and 1138490 identify the same fuse.
Q: What is the difference between the CT 973045 and CT 973043 fuses?
A: The CT 973045 is rated for 200 amps while the CT 973043 is 120 amps. The 200-amp rating protects higher-current primary power circuits, typically main battery disconnect or traction motor circuits. Use only the fuse rating specified for your equipment.
Q: What causes the CT 973045 fuse to blow repeatedly?
A: Repeated fuse failure in a 200-amp primary circuit indicates serious electrical fault: battery short circuit, traction motor failure, wiring damage, or contactor malfunction. Repeated blowing requires electrical diagnosis before fuse replacement.
Q: Are there aftermarket or equivalent 200-amp fuses for the CT 973045?
A: The CT 973045 has documented cross-reference numbers: 113-8490 (supersedes), ACK SK-55240130JE (equivalent). These are OEM alternatives. Always verify voltage rating and bolt-on style match your equipment before ordering replacements.
Q: What is the insulating material and physical dimensions of the CT 973045?
A: The CT 973045 features a thermoset molded base for electrical insulation and durability under high-current conditions. Provide your equipment model for exact dimensions and bolt hole spacing to confirm fitment in the fuse holder.
