2. Advance warning of gas leak by continuous pressure monitoring
3. Fail-safe CB by means of safety membrane for each pole
4. Automatic safety shutters to cover live parts when CB is withdrawn
5. No degradation of main current carrying contacts, as there are separate currents carrying and arcing contacts
