VARITECTOR PU AC I integrated fuse

VARITECTOR PU AC I integrated fuse

VARITECTOR PU AC I integrated fuse Product innovation

The proven surge protection devices of the VPU series are now also available in variants with integrated type I back-up fuse with 25 kA. This eliminates the need for an additional back-up fuse upstream of the SPD. The combined type I+II surge protection devices have one back-up fuse per protective path and can be used universally in power distribution systems.

VARITECTOR PU AC II integrated fuse

VARITECTOR PU AC II integrated fuse Product innovation

In industrial facilities, private and public buildings as well as in systems for regenerative energy generation, the power distribution systems must be equipped with suitable surge protection. This reliably prevents cost-intensive lightning and overvoltage damage. The combined type II+III surge protection devices have one back-up fuse per protective path and can be used universally in power distribution systems.

VARITECTOR PU PV

VARITECTOR PU PV

PV systems are at high risk of lightning strikes due to their installation in exposed locations and must therefore be protected against surges in accordance with EN 51643-32. To avoid system failures, high repair costs and loss of sales due to surge damage, powerful PV arresters are the best solution.

Surge protection is a mandatory component in all commercial and private real estate according to DIN VDE 0100-443 und -534. The space-saving installation on the 40mm rail system guarantees the best protection with the smallest space requirement.

VARITECTOR PU IoT AC

VARITECTOR PU IoT AC

VARITECTOR PU IoT AC Product innovation

Surge protection is becoming more and more important due to increasing digitalization. On the one hand, because the sensitivity of intelligent devices, systems, and infrastructures is growing, and on the other, because cloud communication and the exchange of process data are playing an increasing role.
