FAQ

What contactors is the LADN31 compatible with?

The LADN31 auxiliary contact block is designed for front mounting on TeSys D and TeSys Deca range contactors (models LC1D, LC1DT) and control relays (CAD). Always verify compatibility with your specific contactor model.

What are the screw terminal specifications for the LADN31?

The LADN31 uses screw clamp terminals. They can accommodate one or two flexible cables from 1 to 2.5 mm squared (with or without cable end) or one or two solid cables from 1 to 2.5 mm squared. The recommended tightening torque is 1.2 N.m.

Can I stack multiple LADN auxiliary blocks on a single contactor?

Yes, depending on the contactor model. TeSys D contactors can typically accept one front-mounted and one side-mounted auxiliary contact block. The LADN31 is a front-mounted block. Refer to the Schneider Electric technical documentation for the maximum number and configuration of auxiliary contacts for your specific contactor.
