Product information

Description

The Dehn surge arrester, type T1+T2, is a robust protective device engineered to safeguard electrical installations from dangerous voltage spikes. Designed for high-performance requirements, this 4-pole unit effectively manages both atmospheric and switching overvoltages, ensuring the stability and longevity of connected equipment. Its specialized design makes it an ideal solution for modern e-mobility infrastructure, providing reliable protection for electric vehicle charging stations.

Advantages

This surge arrester offers a dual-stage protection capability, combining the features of Type 1 and Type 2 devices into a single, efficient component. By integrating advanced discharge technology, it provides a high discharge capacity of 12.5kA and 50kA, which significantly reduces the risk of damage from lightning strikes or grid fluctuations. The inclusion of remote signaling (FM) allows for proactive maintenance and monitoring, ensuring that operators are immediately alerted to the status of the protective device. Its compact 4-pole configuration is specifically optimized for e-mobility applications, facilitating seamless integration into charging systems while maintaining high safety standards.

Suitable for

  • Electric vehicle charging infrastructure
  • Commercial and industrial electrical distribution boards
  • Protection of sensitive electronic control systems
  • Installations requiring combined Type 1 and Type 2 surge protection

When it may not be suitable

This device is not intended for use in low-voltage systems that do not meet the specified voltage ratings or in environments where the expected surge currents exceed the device's rated discharge capacity. It is also not suitable for applications requiring specialized DC-specific surge protection unless explicitly verified for the specific circuit configuration.

Key specifications

  • Type: T1+T2 combined surge arrester
  • Poles: 4-pole configuration
  • Discharge capacity: 12.5kA and 50kA
  • Signaling: Integrated remote signaling contact (FM)
  • Application focus: E-mobility and charging infrastructure
  • Voltage rating: 255V

How to use

The surge arrester should be installed by a qualified electrician in accordance with local electrical regulations and safety standards. It is typically mounted on a standard DIN rail within the main distribution board or the charging station's electrical enclosure. Ensure that the connection cables are kept as short as possible to minimize inductive voltage drops during a surge event. The remote signaling contact should be wired to a monitoring system if real-time status reporting is required.

What to consider before purchase

  • Verify the compatibility of the device with your existing electrical distribution system
  • Ensure the installation space meets the requirements for a 4-pole DIN rail mounted device
  • Confirm that the discharge capacity meets the risk assessment requirements for your specific location
  • Check if the remote signaling feature can be integrated into your existing building management or monitoring system

Usage recommendations

Regularly inspect the status indicator on the device to ensure it is functioning correctly. If the indicator shows that the protection has been exhausted, the unit must be replaced immediately to maintain the safety of the electrical installation.
