BLITZDUCTORconnect

Easy. Safe. Robust.

Protects intrinsically safe measuring circuits and bus systems - For maximum system availability

To ensure that safety-relevant systems in the process industry run 24/7, they have to be reliably protected against lightning and surge damage.

The universal BLITZDUCTORconnect combined arrester is the optimal solution.

Different product types and device variants meet the most diverse requirements of automation and measuring and control technology in the process industry. Special Ex-approved product variants are available for intrinsically safe signal circuits.

With a total lightning current discharge capacity of 3 kA and low protection levels, this new generation of devices is optimally suited for protecting terminal devices.

Your benefits

Gain space, optimise staff capacities, reduce costs

With BLITZDUCTORconnect you

Gain space
thanks to an arrester width of only 6 mm

Reduce costs
by using fewer remote signalling units

Save time
since the arrester is installed without tools and no additional disconnection clamps are required.

Increase system availability
as the signal circuit remains available even in case of overload.

How to save time during installation and maintenance
The mechanical status indication always provides a complete overview. Failure of individual arresters due to overload is immediately apparent through the red inspection window.

In addition, the status can be reported directly to a higher-level control system by means of the relevant remote signalling unit.
The active transmitter and receiver unit with passive reverse unit minimises the wiring effort during installation.
Always the right arrester

Compact or modular?

The right arrester for every application

The choice is yours. Compact or modular?
The BLITZDUCTORconnect product family includes both. Especially useful in large-scale systems: All arrester variants have a width of only 6 mm.

Modular arresters consist of a base part and protection module. The module locking mechanism fixes the protection module to the base part and is vibration and shock-tested.
Advantage for maintenance: Only the overloaded module has to be replaced. Thus, surge protection for the system is quickly restored without the need for rewiring.
Easy maintenance thanks to secR module locking

Safe installation without tools

Easy maintenance thanks to secR module locking

In order to precisely remove plug-in modules without accidentally pulling an adjacent module, the secR release buttons are a great practical aid.
Save time during measurements

Safe maintenance without tools

The arrester has a disconnection function, pulling the arrester module, turning it 180° and plugging it into the base part again interrupts the signal circuit. This provides a considerable time benefit when carrying out measurements.

Another plus for the installer:
All installation steps are performed without tools and without installing disconnection clamps.
Keep systems up and running

Fail-open failure mode secures processes

Reliable system availability is a top priority for industry and production. This means that operation should remain uninterrupted, even if an arrester has discharged surges and needs to be replaced.

BLITZDUCTORconnect scores here, too. The fail-open function disconnects overloaded components from the signal circuit. This means that the system circuit remains available, the arrester can be replaced during operation and production processes are not interrupted.
A SINGLE remote signalling unit monitors up to 50 arresters

Monitoring up to 50 arresters

Innovative transmitter and receiver unit

Particularly interesting in the industrial environment: Up to 50 arresters can be monitored by a single unit.
Additional parameterisation of the arresters is not necessary.

Tips for installation

BLITZDUCTORconnect particularly suited for Ex areas

All arresters of the BLITZDUCTORconnect series are approved for use in Ex zone 2. They thus meet the requirements of type of protection "ec".

A special Ex-approved device variant is available for protecting intrinsically safe signal circuits.

All blue arresters of the BLITZDUCTORconnect series meet the requirements of type of protection "ia". They are approved for use in Ex zones 1+2 and for gas and dust applications.

Approvals:

UL, CSA, EAC, SIL, ATEX, IECEx
^{(partly in preparation)}

Accessories:

The Ex(i) partition PARTITION EXI ensures that the minimum distance between intrinsically safe and non-intrinsically safe signal circuits is maintained. When using the surge protection devices in intrinsically safe circuits, this minimum distance ≥ is 50 mm.

Special protection of unearthed 3- and 4-conductor measuring circuits

The special BCO CL4 BC is available for the protection of multi-wire, 3- or 4-conductor measuring circuits in measuring and control equipment, e.g. PT100 temperature measuring circuits. Due to the lack of series impedance, it is not necessary to adjust the signal.

to the product

Easy and safe maintenance

Particularly practical:
The signal is interrupted by pulling the arrester module, turning it 180° and plugging it into the base part again.

This ensures quick and easy measuring without tools.

A considerable time advantage.
