FLASHTRAB SEC T1+T2 is the market's unique type 1+2 special combined lightning current and surge arrester. It is the ideal protection for environments with frequent switching operations. Lightning currents are controlled safely by the powerful spark gap, while dynamic surge voltages are reliably limited by the varistor-based type 2 arresters.

Your advantages

  • Extends service life in sensitive installations with frequent switching operations in particular, thanks to the gentle response behavior of its integrated varistor
  • Saves time, money, and space thanks to use up to 315 A without a backup fuse
  • Uninterrupted system operation through the use of technology-leading spark gaps with safe disconnect devices
  • Easy maintenance thanks to the universally pluggable protective devices

High rated voltage enables worldwide use

Usage range of the FLASHTRAB SEC T1+T2  

Usage range of the FLASHTRAB SEC T1+T2

FLASHTRAB SEC T1+T2 meets the highest requirements of lightning protection level I in accordance with international standard IEC 62305-1. This means that your devices are safely protected against lightning strikes of up to 200,000 A.

Thanks to their high rated voltage of 350 V AC, the arresters can be used worldwide. The type 1+2 special combined lightning current and surge arrester provides reliable protection, even with an unstable power supply with severe mains voltage fluctuations. The voltage protection level is always below 1.5 kV.


UC = maximum continuous voltage
UTOV = TOV requirement according to IEC 61643-1
UN = nominal voltage

Plug-in and removal


Universally pluggable arresters

A major advantage of FLASHTRAB SEC T1+T2: all arresters are universally pluggable. 

To perform insulation measurements, simply remove the plugs. There is no need for complicated disconnection and connection.

In the event of the unexpected overload of individual protective plugs, e.g., due to extremely powerful lightning strikes, you can replace the affected plugs quickly and inexpensively.

Recurring tests for surge protective devices can be performed quickly and easily using the CHECKMASTER 2 test device.

Wiring and marking

Type 1+2 special combined lightning current and surge arrester, rotated  

Arrester can be rotated 180°

The type 1+2 special combined lightning current and surge arrester is symmetrical in design; the base elements and plugs can be rotated through 180°. This offers the following advantages:

  • Installation is extremely easy.
  • The connections are always on the correct side, regardless of whether the supply lines arrive from above or below.
  • Cable lengths are kept to a minimum.
  • The large marking area is always legible.
  • In addition, the two terminal points per channel provide the option of V-shaped through wiring.

Convenient monitoring

FLASHTRAB Safe Energy Control  

Signaling directly on the plug

The operating state of all modes of protection of FLASHTRAB SEC T1+T2 is monitored. Clear signaling takes place directly on the module, without using any power.

A floating changeover contact is also monitored at the same time. This makes it easy to implement maintenance-friendly remote signaling.The benefit for you: You can retrieve information about the state of the type 1+2 special combined lightning current and surge arrester where it suits you best.
