Type 2 AC surge protector - 1-pole - pluggable
Part Number: 821120411
DAC50G-10-440
- Type 2 AC multipolar surge protector
- In: 20 kA
- Imax: 50 kA
- Pluggable module for each phase
- Remote signaling option
- EN 61643-11, IEC 61643-11 certified
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.
