A large number of sensors and actuators are monitored and controlled in applications for measurement and control technology. A failure due to surge voltages can have devastating effects. Our surge protective devices offer an ideal solution and help to avoid system failures for all applications.

Your advantages

  • Protection to suit your needs, thanks to the complete product portfolio for all common signals
  • Versatile use: types and connection technology adapted to the application
  • Easy testing, thanks to pluggable version of surge protective devices
  • Worldwide use in potentially explosive areas, thanks to ATEX and IECEx approvals

TERMITRAB complete – the product range starting from 3.5 mm

TERMITRAB complete product range  

TERMITRAB complete product range

TERMITRAB complete is the world's narrowest surge protection for MCR technology. The product range includes a complete system kit. It covers simple, single-stage surge protection right through to multi-stage, pluggable versions with knife disconnection, signaling, and the option of remote signaling.

The narrowest surge protective devices are just 3.5 mm wide. This represents a space saving of up to 50% in comparison with 7 mm installations.

The protective devices in the TERMITRAB complete range provide mechanical signaling that displays the status of the protective devices without the need for additional auxiliary power. Optional remote signaling modules visually monitor up to 40 protective devices. In the event of a thermal overload, the remote signaling modules notify the control room, for example, of the status in the form of a group message via a floating contact.

 

PLUGTRAB PT- IQ – always know what is going on

PLUGTRAB PT-IQ surge protection  

Clear signal colors for the status of the protective device

PLUGTRAB PT-IQ is a system comprising a supply and remote signaling module as well as the actual surge protective devices. The module supplies the protective devices and provides the group remote signaling for up to 28 protective modules.

A particularly interesting feature is the multi-stage signaling and remote signaling of the protective devices. Each voltage-limiting component of the protective circuit is intelligently monitored.

A yellow status signal indicates that as a result of frequent surge voltages, the performance limit has been reached. The protective devices are still functional. Your system continues to be protected. A replacement is recommended in order to avoid unnecessary service operations.

  • Green: protective device O.K.
  • Yellow: performance limit reached, replacement recommended
  • Red: overloaded, replacement required

SURGETRAB S-PT – installation directly on the field device

SURGETRAB S-PT surge protection  

SURGETRAB S-PT for direct installation on the field device

SURGETRAB are surge protective devices for all common standard signals that are directly attached to the sensor head via their connecting threads. This type of mounting saves time and money, and there is no need for an additional connection box for installing the surge protection.

Connection versions for through and parallel wiring are available. This enables you to connect the circuit breaker in series or in parallel with the interface of the measuring element. Versions with parallel wiring require a second connecting thread on the sensor head.
