Frequently Asked Questions
Q: Which makes and models is the SW82-126 compatible with?
A: The SW82-126 is compatible with Albright and Curtis electric lift trucks that require 24VDC control circuits and high-current DC motor switching. Verify your equipment uses 24VDC coil voltage and requires 100A continuous current switching before ordering.
Q: What materials are used in the construction of the SW82-126 and how durable are they?
A: The SW82-126 features silver alloy contacts designed for repeated duty cycles in industrial DC motor applications. Silver alloy provides superior conductivity and resistance to arcing compared to standard materials, extending contact life in high-current switching environments typical of electric lift trucks.
Q: When should the SW82-126 be replaced?
A: Replace the SW82-126 if it fails to energize when commanded, if contacts chatter or produce visible arcing, if voltage drop across contacts exceeds 100mV at 100A (indicating contact degradation), or if the coil fails to maintain pull-in at rated 24VDC. Field testing confirms these failure modes.
Q: Is there a cross-reference part number for the SW82-126?
A: No cross-reference part numbers are available for the SW82-126. This is a manufacturer-specific part. Use the exact manufacturer part number SW82-126 when ordering to ensure compatibility and proper form factor.
Q: What are the main electrical specifications for the SW82-126 contactor?
A: The SW82-126 is a double pole normally open contactor rated at 100A continuous current with a 24VDC coil voltage. It features a rated fault current breaking capacity of 150A at 96VDC (resistive, UL508), typical voltage drop of 50mV per pole across new contacts at 100A, and coil power dissipation of 7-13 watts in continuous duty. Terminal type is M8 studs with silver alloy contacts.
