Product information

Description

The Eti-Polam ML T123 300/12,5 4+0 RC is a high-performance surge arrester engineered to provide comprehensive protection for electrical installations. By combining protection classes T1, T2, and T3, this device effectively guards against both direct lightning strikes and transient switching surges. It is specifically designed for use in TN-S electrical networks, ensuring that sensitive electronic components and power distribution systems remain safe from voltage spikes.

Advantages

This surge arrester offers a versatile solution by integrating multiple protection levels into a single unit, which simplifies installation and reduces the need for additional components. The 4+0 configuration ensures balanced protection across all phases and the neutral conductor. Furthermore, the inclusion of a remote signaling contact allows for real-time monitoring of the device status, providing immediate notification if maintenance or replacement is required, thereby enhancing the reliability of the entire electrical system.

Suitable for

  • Residential electrical distribution boards
  • Industrial power supply systems
  • Protection of sensitive electronic equipment
  • TN-S network configurations

When it may not be suitable

This device is specifically designed for TN-S systems and may not be compatible with other earthing arrangements such as TN-C or IT systems without appropriate modifications or additional equipment. It is not intended for use in high-voltage transmission lines or environments where the operating voltage exceeds the specified technical limits.

Key specifications

  • Protection classes: T1, T2, T3 (B+C+D)
  • Network type: TN-S
  • Configuration: 4+0
  • Remote signaling contact: Included
  • Application: Lightning and surge protection

How to use

The surge arrester should be installed by a qualified electrician within the main distribution board. It is typically mounted on a standard DIN rail at the point of entry for the electrical supply. Ensure that the connections are secure and that the grounding conductor is properly sized and connected to the main earthing terminal to allow for effective surge dissipation. The remote signaling contact should be wired to a monitoring system if status tracking is required.

What to consider before purchase

  • Verify that your electrical network is a TN-S system
  • Ensure there is sufficient space in the distribution board for the unit
  • Confirm that the voltage ratings match your local power supply
  • Check if remote monitoring integration is necessary for your setup

Usage recommendations

Regularly inspect the status indicator on the device to ensure it is functioning correctly. If the indicator shows that the protection module has reached the end of its service life, replace the unit immediately to maintain the safety of your electrical installation.
