Product information

Description

The Dehn DG SMP TNS 275 is a high-performance combined Type 2 and Type 3 surge arrester specifically engineered for TNS electrical systems. This 4-pole device is designed to safeguard sensitive electronic equipment and electrical installations from transient overvoltages caused by atmospheric discharges or switching operations. With its compact design and advanced Push-in connection technology, it offers a reliable and efficient solution for maintaining the integrity of electrical circuits in both residential and commercial environments.

Advantages

This surge arrester stands out due to its integrated Type 2 and Type 3 protection, which provides a comprehensive defense against voltage spikes in a single unit. The inclusion of Push-in connection technology significantly simplifies the installation process, allowing for quick and secure wiring without the need for specialized tools. Its robust construction ensures a discharge capacity of 20kA, providing consistent performance and long-term durability for critical electrical infrastructure.

Suitable for

  • Residential electrical distribution boards
  • Commercial office building power systems
  • Protection of sensitive electronic devices
  • TNS network configurations

This device may not be suitable for systems operating outside of the specified TNS network parameters or in environments where the expected surge currents exceed the rated 20kA capacity. It is not intended for use in high-voltage industrial transmission lines or as a primary lightning protection system for external building structures.

Key specifications

  • Type: Combined Type 2 and Type 3 surge arrester
  • Poles: 4-pole configuration
  • Discharge capacity: 20kA
  • Connection technology: Push-in
  • System compatibility: TNS systems

Installation should be performed by a qualified electrician in accordance with local electrical safety regulations. The device is mounted on a standard DIN rail within the distribution board. Ensure that the conductors are stripped to the appropriate length and inserted firmly into the Push-in terminals to establish a secure electrical connection. Verify that the system voltage matches the rated voltage of the arrester before energizing the circuit.

What to consider before purchase

  • Verify that your electrical system is a TNS configuration
  • Ensure the installation space on the DIN rail is sufficient
  • Check that the surge current requirements do not exceed the 20kA rating
  • Confirm compatibility with existing circuit protection devices
Regularly inspect the status indicator on the surge arrester to ensure it is functioning correctly. If the indicator shows a fault, the device should be replaced immediately to maintain continuous protection for your electrical equipment.
