Frequently Asked Questions
Q: What is a double-acting contact assembly and what does the AL 2180-30 do?
A: A double-acting assembly means the AL 2180-30 has contact surfaces on both sides of the assembly to complete multiple electrical circuits simultaneously within a single contactor. This design is used in lift truck contactors that require coordinated switching of multiple power circuits.
Q: What materials are used in the AL 2180-30 moving contact assembly?
A: The AL 2180-30 features silver alloy contact tips for high electrical conductivity and weld resistance, with a copper and steel spindle for structural strength. This combination provides both electrical performance and long-term durability in industrial electrical service.
Q: Why are the contact tips weld-resistant on the AL 2180-30?
A: Weld-resistant contact tips prevent the moving and stationary contacts from sticking together during high current arcing or thermal cycling. This property ensures the contactor remains operable and does not freeze in the energized or de-energized position.
Q: Does the AL 2180-30 work in different lift truck contactor designs?
A: The AL 2180-30 is designed as a general-purpose double-acting moving contact assembly for electric lift truck contactors. Cross-reference your specific contactor model against the assembly pocket dimensions and electrical requirements to confirm compatibility before ordering.
Q: What factors affect the service life of the AL 2180-30?
A: Service life depends on load current, switching frequency, ambient temperature, and moisture exposure. The weld-resistant and high-conductivity materials support extended service intervals, but replacement becomes necessary when visual arcing damage appears on the contact surfaces or electrical resistance increases beyond specification.
