Product information

Description

The Eti-Polam ETITEC SM T12 300/25 4+0 is a high-performance combined surge arrester designed to provide comprehensive protection for TN-S electrical power systems. By integrating advanced hybrid varistor and spark gap technology, this device effectively manages both high-energy lightning currents and transient switching surges. It serves as a critical component in safeguarding electrical installations and sensitive electronic equipment from the damaging effects of overvoltages.

Advantages

This surge arrester offers a robust defense mechanism by combining the rapid response of varistors with the high discharge capacity of spark gaps. Its design ensures a high level of reliability in demanding environments, effectively limiting voltage spikes to safe levels. The 4+0 configuration is specifically optimized for TN-S networks, providing a streamlined and efficient installation process while maintaining high operational safety standards.

Suitable for

  • TN-S electrical power distribution systems
  • Industrial facilities requiring lightning protection
  • Commercial buildings with sensitive electronic infrastructure
  • Main distribution boards in residential or office complexes

When it may not be suitable

This device is specifically engineered for TN-S systems and will not function correctly in TN-C, TT, or IT earthing arrangements without appropriate modifications or additional components. It is also not intended for use in circuits where the operating voltage significantly exceeds the specified maximum continuous operating voltage of 300V.

Key specifications

  • Type: T1+T2 (Class I+II) combined surge arrester
  • Network system: TN-S
  • Configuration: 4+0
  • Impulse current (Iimp): 25kA
  • Maximum continuous operating voltage: 300V
  • Technology: Hybrid varistor and spark gap

How to use

The device should be installed by a qualified electrician in the main distribution board at the point of entry for the electrical supply. It must be mounted on a standard DIN rail. Ensure that the connection cables are kept as short as possible to minimize inductive voltage drops during a surge event. Proper grounding must be verified to ensure the device can effectively divert excess energy to the earth.

What to consider before purchase

  • Verify that your electrical network is a TN-S system
  • Check the maximum continuous operating voltage of your installation
  • Ensure there is sufficient space on the DIN rail within your distribution board
  • Confirm that the impulse current rating meets the requirements of your local lightning protection zone

Usage recommendations

Regularly inspect the status indicators on the device to ensure it remains operational. If the indicator shows a fault, the surge arrester module must be replaced immediately to maintain the protection of your electrical system.
