LADN40 Description

Short technical summary and product information.

The Schneider Electric LADN40 is an auxiliary contact block from the TeSys D range, featuring 4 normally open (NO) instantaneous contacts. This component is designed for top mounting and utilizes screw clamp terminals, compatible with wire sizes from 1 to 2.5 mm² for both solid and flexible conductors.

 

Electrically, the LADN40 offers a rated insulation voltage of up to 690V (IEC) and a rated operational voltage of 690V AC at 25-400 Hz. It has a conventional free air thermal current of 10A at 60°C. The block supports a minimum switching current of 5mA and a minimum switching voltage of 17V, with a mechanical durability of 30 million cycles.

 

Environmental specifications include an operating ambient air temperature range of -5°C to 60°C and a storage temperature range of -60°C to 80°C. The product is compliant with various standards including IEC 60947-5-1 and is certified by UL and CSA. It also meets environmental requirements such as RoHS compliance and is free from toxic heavy metals and mercury.
