Features

A high discharge capacity, low protection level and dual safety Thermo Dynamic Control disconnector define the high reliability of the devices.

Applications

- High discharge capacity thanks to powerful discharge gap.
- Quick response
- Reliable control thanks to Thermo Dynamic Control disconnector with dual monitoring
- Slim design (modular construction) according to DIN 43880
- Multifunctional terminals for connection of conductors and busbars

- Complete unit consisting of upper part and base, pre-mounted and ready for connection
- Plug-in arrester with dynamic separating device
