Product details

The Schneider LADN11A is an auxiliary contact block from the TeSys Deca range, configured as 1 normally-open plus 1 normally-closed instantaneous contact. It mounts to the front of a TeSys Deca contactor or reverser and connects via snap-in terminals accepting 1 to 4 mm² flexible or rigid wire.

For motor contactor auxiliaries in AC-15 duty, the rated operational current (Ie) is 6 A at 120 V and 1.04 A at 690 V. For DC-13 inductive loads it is 0.55 A at 125 V and 0.1 A at 600 V. The making capacity is 140 A AC and 250 A DC, rated per the same standard.

Minimum switching capability is 5 mA at 17 V, which covers electronic-level signal switching.

Frequently asked questions

What compliance certifications does the LADN11A carry?

The block complies with EN/IEC 60947-5-1, UL 60947-5-1, CSA C22.2 No 60947-5-1, and GB/T 14048.5. It also meets the glow-wire requirements of IEC 60335-1 Clause 30.2 and IEC 60335-2-40 Annex JJ.

What are the rated currents for the LADN11A at different voltages?

In AC-15 duty the block is rated 6 A at 120 V and 1.04 A at 690 V. In DC-13 duty it is rated 0.55 A at 125 V and 0.1 A at 600 V. The conventional free-air thermal current is 10 A at 60 °C.
