Schneider Electric TeSys Deca Series Auxiliary Contact, 10A Contact Current, 600V Rated Insulation Voltage - LADN22S


This auxiliary contact is an add‑on switching Block designed for front mounting to extend the signalling and control capabilities of contactors in industrial electrical panels. It provides instantaneous changeover contacts in a Compact red housing and connects via screw clamp terminals for straightforward wiring in automation and power distribution assemblies.

Features & Benefits


• 2NO and 2NC contacts enable both signalling and interlocking functions
• 10A conventional thermal current supports routine control loads
• 690V rated operational voltage suits AC networks up to 690V
• 1.04A operational current at high voltage for compatibility with AC‑15 duties
• 30Mcycles mechanical durability minimises replacement frequency
• 5mA minimum switching current allows detection of low‑level signals

Applications


• Suitable for adding auxiliary contacts to control contactors in motor starters
• Ideal for interlock circuits in modular control panels
• used with TeSys D contactor frames for expanded I/O signalling
• Can be used for status feedback to PLCs and monitoring systems

What Terminal sizes does it accept for field wiring?


Screw clamp terminals accept 1 to 4mm² flexible conductors with or without ferrules and 1 to 4mm² rigid conductors, with two‑into‑terminal wiring supported for certain sizes.

How is short‑time current withstand specified?


It endures short‑time currents of 100A for 1s, 120A for 500ms, and 140A for 100ms at 60°C.

What environmental limits govern its operation?


Designed for normal environments, it operates between -5 to 60°C and is rated to 3000m altitude with IP20 protection.

How fast do contacts change state to prevent overlap?


Contact switching incorporates non‑overlap timing of 1.5ms on both energisation and de‑energisation to avoid NC/NO overlap.

Which safety or approvals accompany the unit?


It conforms to IEC/EN standards for control contacts and holds certifications from CB, UL, CSA, CCC, EAC and UKCA.
