Varistor with LED 110-230V AC/DC RZM021FP

Protective module with varistor and LED

This protective module, equipped with a varistor and LED, is a key element ensuring protection for relays in electrical installations. Compact dimensions and light weight facilitate installation, and compatibility with RSZ sockets (1.2 C/O) provides wide application possibilities. The LED indicates the operating status, making diagnostics and quick identification of potential problems easier.

Functionality and application

This module is designed to work with relays, functioning as protection against overvoltages and disturbances. The varistor absorbs excess energy, protecting sensitive relay components from damage. Using the module increases the reliability of the entire control system and reduces the risk of downtime in industrial equipment. Thanks to the universal AC/DC voltage range (110-230V), the module is flexible in application and can be used in various electrical network configurations.

Advantages for installers and users

• Relay protection: The varistor effectively protects against the effects of overvoltages, extending the life of relays.
• LED indication: The built-in LED facilitates monitoring of the module status and quick diagnosis of any failures.
• Compatibility: The module is compatible with popular RSZ sockets (1.2 C/O), simplifying integration with existing systems.
• Universal voltage: The ability to power with both alternating current (AC) and direct current (DC) increases installation flexibility.
• Harmony system element: As part of the Harmony range from Schneider Electric, this module works with other control and signaling elements, creating a coherent and efficient industrial solution.
• Support for reliability: The use of Harmony control elements and Zelio relays translates into increased operational efficiency and equipment reliability in demanding industrial conditions.
