Frequently Asked Questions
Q: Which Albright contactors use the AL 2180-28 moving contact assembly?
A: The AL 2180-28 is compatible with Albright SW180L series solenoid contactors found in electric lift trucks. This assembly is not interchangeable with the standard SW180 or other Albright series contactors.
Q: What does large tip configuration mean on the AL 2180-28?
A: The large tip configuration refers to an oversized silver-alloy contact surface designed for heavy-duty cycling and higher continuous current capacity. The SW180L with this assembly is rated for 150A continuous current under normal operating conditions.
Q: What related contact kits are available for SW180L contactors?
A: Related parts for SW180L contactors include the 2180-26 fixed contact stud and the 2180-42A contact kit, which also uses large tip configurations. Verify your contactor design before substituting one assembly for another.
Q: Is the AL 2180-28 designed for single-acting or double-acting applications?
A: The AL 2180-28 is configured for single-acting applications within the SW180L solenoid contactor. Do not use this assembly in double-acting contactor designs.
Q: How does the AL 2180-28 handle repeated electrical cycling?
A: The silver-alloy material and large contact area design resist welding and erosion during heavy-duty cycling typical of electric lift truck operation. Expected service life depends on switching frequency and load conditions, but the material composition supports thousands of cycles before replacement is needed.
