Pluggable single-pole Surge Arrester
- Multi-purpose surge arrester consisting of a base part and a plug-in protection module
- High discharge capacity due to heavy-duty zinc oxide varistor
- High reliability due to "Thermo Dynamic Control" SPD monitoring device
- Energy coordination with other arresters of the Red/Line product family
- Operating state / fault indication by green / red indicator flag in the inspection window
- Narrow (modular) design acc. to DIN 43880
- Multifunctional terminals for connecting conductors and busbars
- Easy replacement of protection modules due to module locking system with module release button
- Vibration and shock-tested according to EN 60068-2
DEHNguard S ... FM: With remote signalling contact for monitoring device (floating changeover contact)
Experience of decades in the world market of surge arresters has further improved the latest DEHNguard generation compared to the previous devices.
The unique module locking system fixes the protection module to the base part. Neither vibration during transport nor the enormous forces of discharge can loosen this connection. Nevertheless, the modules can be easily replaced without tools by simply pressing the easy-to-use module release button of the protection modules.
Every base part and protection module is mechanically coded to ensure against installing an incorrect module.
As with all DEHNguard surge arresters, the user of DEHNguard S can rely on the dual "Thermo Dynamic Control" SPD monitoring device which ensures a maximum degree of safety, even under harsh environmental conditions in the world market. The green and red indicator flags shows the operating state of DEHNguard S surge arresters. Apart from this standard visual indication, DEHNguard S ... FM features a three-pole remote signalling terminal. As the remote signalling contact is designed as a floating changeover contact, the remote signal can, depending on the circuit concept, be used as a make or break contact. The multifunctional terminals of DEHNguard S surge arresters are suitable for connecting conductors and busbars, allowing easy wiring with other DIN rail mounted devices. Thus, a wide range of applications can be easily connected in series according to IEC 60364-5-53 for optimal protection.
