Type 2 AC surge protector - 3-phase

DAC50S-30-150

Part Number 821110123

Type 2 AC surge protector
In: 20 kA
Imax: 50 kA
Pluggable module for each phase
Remote signaling
EN 61643-11, IEC 61643-11 compliance

The pluggable surge protectors Type 2 DAC50, are designed to protect AC powerline at the main switchboard of the installation. These SPDs are based on high energy varistor equipped with thermal disconnector and failure indicator, to comply with standards and to provide a maximum protection efficiency, a high impulse current capability and an improved reliability. The surge protectors DAC50 are available in multipolar version and in several voltages to protect single or 3-phase networks.
