Surge protection with 4+0 circuit

The world’s narrowest type 2 surge protective device, Valvetrab SEC, is now also available with a 4+0 circuit.


This version can be used in TN-S and IT power supply systems. Delivering a high continuous voltage of 440 V AC, the extremely powerful surge protective device protects systems in the 400/690 V AC voltage level.


The new type 2 protective device extends the existing SEC product range. With 12 mm per position, the extremely compact design offers all the advantages of space-saving installation. The protective devices are pluggable, which means that they can be easily replaced during servicing. The plugs are mechanically coded, ruling out the possibility of mismatching. The high-performance disconnect device and high-quality components ensure that the system receives uninterrupted protection. Downstream subsections are also protected thanks to the low voltage protection level.
