FAQ

What is the coil voltage for this specific LC1D12?

The coil voltage is not specified on the label of this particular item. It is critical to confirm your control circuit’s required coil voltage (e.g., 24V AC, 230V AC) and ensure it matches the contactor before installation.

Can I add more auxiliary contacts to this contactor?

Yes, the TeSys D series is modular. You can mount additional auxiliary contact blocks, such as the LADN or LADC series, to the front or side to expand the number of NO and NC contacts for more complex control logic.

What is the difference between AC-1 and AC-3 ratings?

AC-1 is for non-inductive or slightly inductive loads, like resistance heaters, and allows for a higher current (25A for this model). AC-3 is specifically for switching squirrel-cage motors, which is a more demanding application, hence the lower current rating (12A for this model) to safely handle starting currents.
