FAQ

What is the coil voltage for this specific LC1D12 contactor?

The coil voltage is not explicitly marked on the outer casing of this unit. It is typically printed on the coil itself, which may require partial disassembly to view. Please test or verify the coil voltage before installation.

Can I add more auxiliary contacts to this TeSys D contactor?

Yes, the TeSys D series is modular. You can add front-mount (LADN) or side-mount (LADS) auxiliary contact blocks to expand the number of NO and NC contacts as needed for your application.

What is the difference between an AC-1 and an AC-3 rating for a contactor?

The AC-1 rating (25A for this model) is for non-inductive or slightly inductive loads, like resistance heaters. The AC-3 rating (12A for this model) is for squirrel-cage motors and involves switching the motor during starting, which is a more demanding application. Always use the AC-3 rating for motor control.
