Datasheet
The pluggable surge protectors Type 2+3 DAC50VG, are designed to protect AC powerline at the main switchboard of the installation.
Equipped with the exclusive CITEL’s VG technology, the range achieves an improved protection level and a total absence of leakage current, guaranteeing a maximum protection efficiency, a simplification of use (no additional SPD required) and a maximum lifetime.
The surge protectors DAC50VG, are available in multipolar version and in several voltages to protect single or 3-phase networks.
