Two arresters, one device – combined lightning and surge protection

The coordinated solution: FLASHTRAB compact is a combination of type 1 lightning arresters and type 2 surge protection.

Optimum combination

Combined type 1 + 2 surge protection with FLASHTRAB compact

FLASHTRAB compact combines universally plug-in capable, encapsulated type 1 lightning arresters and powerful, complete type 2 surge protective devices for the power supply. 

The result is a protective device that is optimally coordinated and can be easily planned and installed.

The direct parallel connection of both arrester types is based on the principle of active energy control or AEC. Here, the lightning arresters are equipped with a starting aid to trigger the operate voltage.

High rated voltage enables worldwide use

FLASHTRAB compact protection combination

FLASHTRAB compact meets the highest requirements of Lightning Protection Level I according to international IEC 62305-1 standard.

This means that your devices are safely protected against lightning strikes of up to 200,000 A.

Due to the high rated voltage of 350 V AC, the arresters can be used worldwide, even with an unstable power supply with high mains voltage fluctuations.

The protection level of the arrester combination is always below 1.5 kV.

Plug in and remove

FLASHTRAB compact: Plug-in arresters

The major advantage of FLASHTRAB compact is that all arresters are universally plug-in capable, including the N-PE spark gap.

  • To perform insulation measurements, simply remove the plugs; complicated disconnection and connection have been eliminated
  • In the event of the unexpected overload of individual protective plugs - due to extremely powerful lightning strikes, for example - you can replace the affected plugs quickly and inexpensively
  • Recurring tests for surge protective devices can be performed quickly and easily using the CHECKMASTER arrester test device from Phoenix Contact


Wiring and labeling

Arresters can be rotated 180°

FLASHTRAB compact has a symmetrical design, allowing the base elements and plugs to be rotated 180°.

This flexibility benefits you:

  • Installation is extremely easy
  • Connections are always on the correct side, regardless of whether the supply lines are led from above or below
  • Cable lengths are kept to a minimum
  • Labeling is legible at all times


User-friendly monitoring

Safe signaling with FLASHTRAB compact from Phoenix Contact  

Signaling directly at the plug

The operating state of all protective paths of FLASHTRAB compact is monitored.

In the event of an error, the L-N plugs are thermally disconnected. Signaling takes place directly at the module, without power consumption.

Monitoring also has a simultaneous effect on the floating PDT contact, allowing easy-maintenance and remote signaling to be implemented.

This gives you the ability to have your arresters indicate their state at whichever location suits you best.
