FAQ

Question?
What is the purpose of the included LAD4TBDL module?

The LAD4TBDL is a bidirectional peak limiting diode transient suppressor. It is designed to protect the DC control circuit from voltage surges and transients when the contactor coil is de-energized, preventing damage to sensitive electronics like PLCs.

Question?
Can this contactor be used for a single-phase motor?

Yes, while it is a 3-pole contactor designed for three-phase applications, it can be used for single-phase motors. For proper operation, you should wire the poles in series or parallel according to the motor’s current requirements and manufacturer guidelines to ensure proper load distribution across the contacts.

Question?
What is the difference between the AC-3 rating (9A) and the Ith rating (25A)?

The AC-3 rating (9A) is the operational current for switching squirrel-cage motors during starting and running. The Ith rating (25A) is the conventional free air thermal current, which is the maximum current the contactor can carry continuously in open air without exceeding temperature limits, typically used for resistive loads.
