TeSys K 4NC instantaneous contact block screw terminals LA1KN04

Instantaneous contact block – reliable control and signaling

TeSys K instantaneous contact block with four normally closed contacts (4NC) is a key element for expanding TeSys K contactors, providing additional control and signaling functions. Mounted on the front of the contactor, it offers convenient screw connection, facilitating installation and wiring. This solution is ideal for both professional installers and end-users who need to increase the capabilities of their electrical installations.

Design and application

The LA1KN04 block is designed to work with LC.K, LP.K and CA.K contactors. Its design based on a snap-on front mounting guarantees a secure and durable connection. It provides contacts with a rated operating current of 10A at 230V AC (AC-15), making it suitable for a wide range of applications in control and protection circuits. It is used where reliable circuit status signaling or additional control functions are required.

Advantages and benefits

• Versatility: ability to expand existing TeSys K contactors with additional auxiliary contacts.
• Convenient installation: front mounting with snap-on – quick and secure installation method.
• Safety: compliance with IEC, UL, CSA and CCC standards ensures safe use in various conditions.
• Durability: high quality workmanship guarantees long life and reliable operation – the block withstands up to 1.5 million switching cycles.
• Ecology: Green Premium certificate confirms compliance with RoHS and REACH regulations, promoting sustainable development.
• Universality: the same additional accessories fit contactors of different power ratings – from 9A to 150A – simplifying storage and component selection.
• Fast reactions: switching frequency up to 1 time per second allows for dynamic circuit control.
• Built-in mirrored contacts: provide flexibility in control circuit configuration.

This contact block is not only an element expanding the functionality of TeSys K contactors, but also an investment in the reliability and safety of your electrical installation.
