- On/OFF indicator
- Universal clamp
- Manual tripping/locking and optional closing device
- Easy installation and operation
HIGH RELIABILITY
- Maintenance-free concept
- Solid Dielectric insulation
- Climate-independent
- Simple operating PMA mechanism
- Up to 3000m altitude, it ensure the rated insulation and interrupting capabilities.
