Description

DEHNvario product line – Surge or combined arresters in a compact DIN rail mounted enclosure.

Innovative enclosure concept
The innovative enclosure design provides maximum functionality on minimum space. In addition to the standard catalogue products, the enclosure concept offers flexibility in terms of space and different connection systems to implement customised and application-specific solutions (upon request). Supplemented by solution-oriented surge protection, the integrated customer function can be protected from possible interference by lightning strikes and surges.

Terminals with direct plug-in technology
The different types feature terminals for conductor connection with direct plug-in technology. This allows easy connection of conductors without tools. The spring-loaded terminals apply a defined pressure on the conductors which automatically equalises any deformation of connected conductors and prevents self-loosening of the wires. The plugged-in conductors can be easily released at the push of a button and individually removed from the relevant terminal.
The terminal unit is snapped into the enclosure and is thus vibration-proof in all environmental conditions. Easy and fast arrester replacement is ensured by removing the terminal units from the enclosure using an unlocking tool or screw driver. Thus there is no need to disconnect the cores individually. Thanks to the integrated test openings in the terminal units, the signal circuit can be tested efficiently even when wired. The signal lines can be contacted by means of a test pin (max. diameter of 1 mm) (device must be installed).

Safe and easy earthing
The lightning and impulse current carrying earth contact allows the arresters to be easily connected to the equipotential bonding via the DIN rail without requiring an equipotential bonding conductor.
