TeSys Deca Auxiliary Contact Block

The Schneider Electric LADN22 is an instantaneous auxiliary contact block designed for TeSys Deca contactors and control relays. It adds four extra contacts to the control circuit, giving installers additional signalling or interlocking capacity in motor-starter and automation panels.

Sustained-load behaviour

The block carries a continuous thermal current of 10 A at up to 690 V AC, so it handles long-duration coil-holding and status-feedback duties without derating. NC mirror certification ensures the normally-closed contacts reliably reflect the main-pole state even after thousands of operations.

Upgrade context

It replaces a missing or worn front-mount auxiliary block on LC1D, LC1F or CAD devices when extra normally-open and normally-closed circuits are required. The jump is worth it when the existing contactor has no free auxiliary positions left and the application demands certified mirror contacts for safety interlocks.

Questions about this item

Does the 10 A auxiliary contact block generate noticeable heat or noise when energised continuously?

It is a passive electromechanical contact block with no fan or active electronics, so it runs silently and produces only minimal heat from contact resistance at rated load.

Which contactor or relay must I already own for the clip-on front mounting to work?

It mounts directly on TeSys Deca contactors LC1D, LC1F and control relays CAD; no separate bracket or adapter is required.

Will the screw-clamp terminals accept the same wire gauges I use on my older TeSys Deca contactors?

Yes, the block uses standard screw-clamp terminals compatible with the wiring practice of existing TeSys Deca contactors and CAD relays.
