LA2KT2U

What does this timer accessory do?

This unit is an electronic on-delay auxiliary contact block designed for TeSys K equipment. It introduces an adjustable time delay before the auxiliary contact changes state, which can help sequence operations in control circuits more smoothly.

What type of contact configuration does it have?

It provides 1 changeover contact (1 C/O). This gives a single timed auxiliary contact that can be used for switching signalling or control functions after the selected delay period.

What is the adjustable time range?

The delay range is adjustable from 1 to 30 seconds. This allows the device to be used for short timing functions where a controlled start delay is required.

Is this an on-delay or off-delay timer?

It is an on-delay type. That means the contact changes state only after the preset time has elapsed following energisation.

What control voltage is it designed for?

This timer block is intended for a 110 to 240 V AC control circuit. In the LA2KT2U specification, the signalling circuit is rated up to 240 V AC.

Which Schneider ranges is it compatible with?

It is designed for use with TeSys K devices and is listed as compatible with LC1K, CA2K, CA3K and CA4K series units. It is a front-mounted accessory, so it is suited to applications where the matching TeSys K platform is already in use.

Where is the accessory mounted?

It is fitted at the front of the compatible device. This front-mount arrangement makes it suitable for compact panel layouts where space and straightforward integration are important.

What terminal style does it use?

The unit uses slip-on terminals. This connection style is commonly selected for quick and practical wiring in control panel assemblies.

What are the main physical dimensions?

The approximate dimensions are 27 mm high, 38 mm wide and 38 mm deep, with a net weight of around 0.04 kg. Its compact size makes it a practical choice where panel space is limited.

What is the current rating for the signalling circuit?

The conventional free-air thermal current is 2 A for the signalling circuit. This makes it suitable for auxiliary and signalling duties rather than high-power load switching.

What level of environmental protection does it offer?

The device has an IP20 degree of protection and is intended for normal industrial environments. The stated operating ambient temperature range is -10 to 60 °C.

How quickly does it reset?

The stated reset time is 1.5 seconds during the time delay and 0.5 seconds after the time delay. This can be useful when assessing how the timer will behave in repeated operating cycles.
