PLUGTRAB PT - Solution-oriented surge protection for MCR technology

Especially in the area of measurement and control systems, often a multitude of lines must be protected from surge voltages. With TRABTECH surge protection and the PLUGTRAB PT product family it's no problem.

With a width of only 17.5 mm (1 div.), you can protect up to five signal lines, two double wires or a four-conductor measurement from surge voltages.

This means that not only the assembly in the control cabinet remains easy, but even the installation costs are minimized.

Universal pluggability

Another enormous advantage is the universal pluggability of the PLUGTRAB PT product family. Thanks to this feature, replacing faulty plugs when servicing is necessary is inexpensive.

Even the servicing is considerably simplified. For example, isolation measurements are possible without disconnection or influencing the signals. The plug guide on the base elements ensures safe plugging in and contacting, and the plug coding offers maximum installation safety.

Innovative shielding concepts

With PLUGTRAB PT, you can choose between direct and indirect ground connection of the shield potential. The different base elements make this possible. For the types PT...+F-BE, the shield potential is indirectly grounded via a gas discharge arrester. Alternatively, the direct grounding is possible using the DIN rail. With the optionally available shield fast connection, one can quickly and easily attach the shield to the corresponding screw terminal block.

PLUGTRAB PT/FM - the intelligent MCR protective circuit with self diagnosis

Especially for the field of MCR technology, PLUGTRAB PT/FM offers a surge protection device, which can: monitor itself and report the status. A built-in diagnostic unit that monitors the protective circuit electrically ensures this. That provides you highest safety.

The status is displayed directly on the connector of the protection module. Moreover, the status can be signaled to a central control room without additional space requirement.

Conclusion

Failure of the signal circuits of MCR technology due to surge voltages can result in large scale damage. When selecting surge protection devices for MCR technology, it is recommended that a convenient installation using two-part devices - base element and protective connector - be ensured, apart from meeting the technical specifications.

A voltage coding of the protective connectors and the integrated status displays coupled with a floating remote indication contact additionally offer high installation safety as well as the option of integrating the devices in condition monitoring systems.
