Frequently Asked Questions
Q: What are the electrical ratings for this GE 12VDC contactor?
A: The GE 1C4482CTSA100B012AA features a 12VDC coil voltage and 180A continuous contact rating with SPST normally open configuration. Switching delay is 50ms on and 10ms off. Main terminals accept AWG 16-10 copper conductors. This high-speed design is optimized for rapid switching in electric lift truck main power circuits.
Q: Is this a direct replacement for OEM part number 1C4482CTSA100B012AA?
A: Yes. This unit is a direct replacement for GE OEM part number 1C4482CTSA100B012AA. Confirm that your equipment uses 12VDC system voltage and requires 180A continuous switching before ordering. Verify mounting dimensions match your vehicle main contactor location.
Q: What equipment types use this 12VDC 180A contactor?
A: This contactor is used in 12VDC electric lift trucks, electric pallet jacks, stackers, and reach trucks from Crown, Toyota, Raymond, Yale, and similar OEM manufacturers. It handles main battery disconnect and power circuit control functions. Confirm your vehicle electrical schematic specifies 12VDC and 180A rating before purchasing.
Q: What terminal sizes and conductor gauges are required?
A: Main terminals are sized for AWG 16-10 copper conductors. Use appropriately sized wire lugs and ensure all connections are torqued per equipment manufacturer specifications to prevent arcing and contact degradation. Incorrect wire gauge or loose connections cause rapid contact wear and premature failure.
Q: How do I identify when this contactor needs replacement?
A: Replace the contactor if switching noise exceeds 25dBA, if contacts show visible pitting or erosion, if the coil fails to energize at 12VDC, or if there is hesitation or grinding during on/off cycling. Contact deterioration reduces amperage capacity and increases risk of circuit failure. Preventive replacement during routine maintenance extends equipment reliability.
