Frequently Asked Questions
Q: What are the voltage and amperage specifications for the AL SW88-24?
A: The AL SW88-24 is a 24VDC single pole double breaking contactor with a 100A thermal continuous rating. Intermittent ratings are 185A at 30% duty cycle, 160A at 40% duty, and 140A at 50% duty cycle. Terminal studs are M8 size for secure DC motor connections.
Q: What electric lift truck models use the AL SW88-24 contactor?
A: The AL SW88-24 is compatible with 24VDC electric lift trucks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and other OEMs. It is designed for DC motor reversing applications. Cross-reference part numbers include ALSW88-24, ALSW8824, and SW8824.
Q: What does double breaking mean and why does it matter?
A: Double breaking means the contactor has two independent contact points breaking the load circuit simultaneously. This design improves reliability in DC motor control by ensuring faster load interruption and reduced arcing, critical for safety-sensitive material handling operations.
Q: How durable is the AL SW88-24 for long-term use?
A: The AL SW88-24 is mechanically rated to exceed 5 million cycles, making it suitable for frequent direction changes and motor reversing in heavy-duty warehouse and factory lift truck environments. This durability rating exceeds typical OEM contactor lifespan.
Q: Can the AL SW88-24 replace my existing contactor?
A: The AL SW88-24 is a direct replacement for compatible electric lift truck models. Verify coil voltage (must be 24VDC), M8 terminal stud compatibility, and that your truck uses a single pole double breaking reversing design. Confirm part cross-reference before ordering.
