2. “Line 4” panel connectors that allow a fast and secure connection. These are equipped with caps to ensure a 65 degree protection.
3. Surge protection devices: 20kA (8/20), available in 600Vdc or 1000Vdc version to match voltage effectively generated by the system.
4. DC circuit breaker with 600Vdc or 1000Vdc nominal voltage. It’s ideal for protection and isolation for maintainance of solar strings in total safety. With handle and padlock.
5. Thermal magnetic circuit breaker with RCCB, single phase and three phase, A or AC class, with 300mA sensibility and interruption power of 6kA or 10kA.
6. AC SPD of 20kA, available on single phase and three
   phase version.

Every cabur photovoltaic electrical panel is provided together with all the documentation necessary to certify the photovoltaic system:

• The installation manual with the risk assessment document, in compliance with CEI EN 61439-2.
  This document contains all information about possible risks during the installation and maintenance.
