Frequently Asked Questions
Q: What voltage range does the AL SW180-36 contactor support?
A: The AL SW180-36 is rated for 36/48 volts. Coil voltage can be ordered from 6V to 240V depending on application requirements. Confirm your lift truck voltage before ordering.
Q: What are the current ratings for the AL SW180-36?
A: The AL SW180-36 is rated at 200A for resistive loads and 150A for inductive or capacitive loads. These ratings assume proper cooling and terminal connections. Undersized electrical wiring or corroded terminals will reduce actual current-carrying capacity.
Q: What cross-reference part numbers match the AL SW180-36?
A: The AL SW180-36 is equivalent to ALSW180-36, ALSW18036, and SW18036. All reference the same Albright SW180 series contactor for 36/48-volt electric lift trucks.
Q: How much voltage drop occurs across the AL SW180-36 contacts?
A: Typical voltage drop is approximately 40mV per pole under rated current. Excessive voltage drop indicates contact wear or loose terminal connections and requires inspection or replacement.
Q: Is the AL SW180-36 suitable for wet environments or cold storage?
A: Standard contactors perform best in dry environments. If your lift truck operates in wet or cold storage conditions, verify enclosure rating and terminal sealing. Corrosion accelerates contact failure in high-moisture or freezing environments.
Q: What is the mechanical durability rating for the AL SW180-36?
A: The AL SW180-36 exceeds 5 million mechanical cycles. Lifespan depends on electrical load type, switching frequency, and preventive maintenance such as keeping terminals clean and connections tight.
