Frequently Asked Questions
Q: What equipment does the Albright DC182-3 contactor fit?
A: The Albright DC182-3 is a 24VDC motor-reversing contactor designed for industrial electric lift trucks from Crown, Toyota, Raymond, Yale, Hyster, and other major manufacturers. It is used in direct-drive DC motor circuits for forward-reverse control. Verify your lift truck voltage and motor circuit before ordering to confirm compatibility.
Q: What are the key specifications of the DC182-3?
A: The DC182-3 features a 24VDC nominal coil voltage, 150A continuous current rating, 6 to 96 VDC main circuit voltage rating, double-breaking silver-alloy contacts, a pull-in voltage of 14.5 VDC maximum, 17 Ohm coil resistance, and a 5,000,000 mechanical cycle life. It is rated for intermittent duty operation typical of lift truck motors.
Q: What are the cross-reference and interchangeable part numbers for the DC182-3?
A: The Albright DC182-3 replaces the older SW182 model, supersedes the DC182B variant, and is directly interchangeable with DC182-100 and DC182-102 contactors. Verify your equipment documentation before substituting these parts to ensure wiring and terminal configurations match your lift truck control system.
Q: What failure symptoms indicate a DC182-3 contactor needs replacement?
A: Common failure signs include the motor not responding to forward or reverse control commands, visible arcing or pitting on the silver-alloy contacts, a stuck plunger that does not move smoothly, chattering or buzzing sounds when the coil is energized, or loss of one direction (forward works but reverse does not, or vice versa). Any of these symptoms indicates contact wear or coil failure requiring replacement.
Q: How long does the DC182-3 typically last in electric lift truck service?
A: The DC182-3 has a rated mechanical life of 5,000,000 electrical cycles. In typical warehouse lift truck use, this translates to 8 to 15 years of service depending on daily usage frequency, environmental conditions, and electrical stress. Regular inspection of contact wear can help predict replacement timing.
Q: Can the DC182-3 be used on lift trucks with different voltage systems?
A: The DC182-3 is designed specifically for 24VDC coil voltage and will not function properly on 12VDC or 48VDC systems. The main circuit accepts 6 to 96 VDC, but the control coil must receive 24VDC to energize correctly. Do not force this contactor onto a lift truck with a different control voltage.
