Varistor filter 24/48V AC/DC LA4SKE1E

Power supply protection and stabilization – Schneider Electric varistor filter

The LA4SKE1E varistor filter is a protective element designed to protect electrical circuits from overvoltage. Its versatility stems from the possibility of use in both AC and DC powered installations. This makes it a reliable solution in a wide range of industrial and automation applications.

Application and functionality

A varistor is an electronic component whose task is to suppress voltage transients – short-term but potentially harmful voltage spikes. The LA4SKE1E filter effectively protects sensitive devices from damage caused by disturbances in the power supply network, such as pulses generated during switching of inductive loads or atmospheric discharges. It works on the principle of non-linear resistance, which increases with increasing voltage, dissipating excess energy and stabilizing the voltage at a safe level.

Characteristics and mounting

The LA4SKE1E varistor filter operates in the voltage range of 24-48V AC/DC, making it compatible with most standard control and automation systems. It should be noted that this filter does not have a built-in LED indicator signaling its operating status. It is part of the TESYS series from Schneider Electric, which guarantees high quality workmanship and compliance with applicable safety standards. Installation is simple and intuitive, and the small dimensions allow integration of the filter even in limited space.

Benefits of use:

• Overvoltage protection: Protects connected devices from damage caused by disturbances in the power supply network.

• Versatility: The possibility of use in both AC and DC installations increases the range of applications.

• High quality: Schneider Electric product – a guarantee of reliability and durability.

• Simple installation: Facilitates integration with existing control systems.

• Compact dimensions: Allow installation even in tight spaces.
