DEHNguard® 5 kA
Compact Surge Arrester
- High reliability due to "Thermo Dynamic Control" monitoring system
- Easy installation and retrofitting thanks to narrow design (width of 18 / 36 mm)
- Application-optimised discharge capacity of 5 kA (In) / 15 kA (Imax) (8/20 µs) per pole
- Energy coordination with other arresters of the Red/Line family
- Operating state / fault indication by green / red indicator flag in the inspection window
- Vibration and shock-tested according to EN 60068-2

Details
The compact surge arresters of the DEHNguard TT 5 275 series complement the proven DEHNguard M family for applications with reduced technical parameters.
DEHNguard TT ... 5 275 arresters takes up little space and are therefore ideally suited for retrofitting into existing installations and applications with restricted space. Consequently, the devices can be used to protect individual parts of installations (e.g. lighting systems or pumps). In case of multi-phase application, e.g. in TT systems (3+1), the arresters only require two modules. Since the devices can be used up to 63 A without additional backup fuse, easy and cost-optimised installation of surge protective devices is ensured.
In this context, the safety-relevant features of the DEHNguard series were not neglected. The DEHNguard 5 kA devices are provided with a “Thermo Dynamic Control“ monitoring device which meets the high safety standards for surge arresters.
The dual Thermo Dynamic Control monitoring device is not only developed based on applicable national and international product standards, but also stands for experience of decades in the world market of surge protective devices and considers many practical applications where arresters might be damaged.
The standard mechanical operating state / fault indication reliably indicates the status of the surge protective device.
Consequently, the devices of the DEHNguard TT 5 275 series are ideally suited forretrofitting, applications with restricted space and reduced technical requirements.
