Frequently Asked Questions
Q: What makes the AL DC182-561L a heavy-duty contactor?
A: The AL DC182-561L features double breaking main contacts with silver alloy tips, M8 main terminals, and direct bracket mounting. It is rated for 150A continuous current and up to 275A intermittent at 30 percent duty cycle, making it suitable for demanding reversing motor applications in industrial lift trucks.
Q: What are the intermittent current ratings and duty cycles?
A: The AL DC182-561L supports 275A intermittent current at 30 percent duty cycle and 235A at 40 percent duty cycle. These ratings allow for higher transient currents during acceleration and deceleration cycles typical in lift truck operations.
Q: How durable is the AL DC182-561L in high-cycle applications?
A: The AL DC182-561L exceeds 5,000,000 mechanical duty cycles. The double breaking contact design and silver alloy contact material provide superior arc suppression and extended contact life under frequent switching.
Q: What coil voltage range does this contactor support?
A: The AL DC182-561L is compatible with a wide coil voltage range. Confirm the specific coil voltage required by your lift truck model, as Albright offers variants for 24V, 48V, and other DC supplies.
Q: Which lift truck brands use the AL DC182-561L style contactor?
A: Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, and CAT electric lift trucks use heavy-duty Albright DC182-561L style reversing contactors. Verify your equipment serial number and OEM part specifications to confirm compatibility.
Q: What is the silver alloy contact material used for?
A: Silver alloy contacts on the main terminals provide superior electrical conductivity, lower contact resistance, and enhanced arc extinguishing capability. This material withstands the high currents and switching stresses of motor reversing applications without excessive arcing or contact erosion.
