Schneider Electric TeSyS K Surge Suppressor for use with TeSys K Series LA4KA1U

Schneider Electric LA4KA1U Surge Suppressor is an accessory designed specifically for integration with TeSys K Series motor starter assemblies. This device provides essential transient suppression and EMI/RFI damping to protect sensitive motor-control equipment and control circuits.

The suppressor accommodates a wide control voltage range of 110 to 250 volts, supporting various supply systems commonly used in industrial automation. It features an RC circuit design which effectively reduces electromagnetic interference and oscillatory ringing that can degrade control signal integrity.

Installation is facilitated by a convenient clip-on, front-side mounting method allowing tool-less attachment to compatible TeSys K series contactors or motor starters, enabling fast retrofit and maintenance operations. Local LED indication is provided for immediate visual status feedback, simplifying system diagnostics.

Engineered for durability, the suppressor carries IP2X basic ingress protection to ensure safe access when panels are checked and undergoes a protective treatment rated TC for humidity and thermal stress resistance. It complies with recognized electrical safety standards including UL 60947-5-1, EN/IEC 60947-5-1, and CSA C22.2 No 60947-5-1, verifying its suitability for switchgear control devices.

Operational temperature ranges from -25°C to 50°C with a storage capacity between -50°C and 80°C, making it suitable for a wide variety of industrial environments. This unit is ideal for use in automation panels, industrial relay bays, and as a replacement component for worn or degraded suppressors within motor-control assemblies.

Supports a control voltage range of 110 to 250 V to accommodate diverse supply systems. Maximum peak withstand capability protects against voltage spikes up to three times control voltage. RC circuit design minimizes EMI/RFI interference for enhanced control circuit reliability.

Clip-on front-side mounting allows easy installation on TeSys K motor starters and contactors. Local LED indicator simplifies operational status and maintenance diagnostics. IP2X ingress protection ensures operator safety during panel checks.

Certified to UL, EN/IEC, and CSA electrical standards for control device compatibility. Temperature rated for operation from -25°C to 50°C, suitable for industrial settings. Designed for retrofit applications reducing EMI/RFI in control circuits and relay bays.

Replaces degraded suppressor units to maintain motor-control assembly performance.

This surge suppressor is an essential accessory within industrial automation and motor control systems, providing protection and enhancing the longevity and performance of TeSys K series motor starters. Its robust design, certification, and ease of installation make it well suited for manufacturing, HVAC, water treatment, and other critical industrial applications.
