The Vartec TII/VVM/255V/20kA varistor module is designed to protect electrical circuits from impulse overvoltages. The device belongs to the TII/C class and provides reliable voltage limitation in alternating current networks.
Main Parameters:
- Maximum continuous AC voltage: 255VAC
- Rated impulse current handled: 20kA
- Maximum branching current: 40kA
- Protection level (operating voltage): 1.5kV
- Power loss: 0.05W
- Operating temperature range: from -40°C to +80°C
Constructive Characteristics:
The module is manufactured in a gray plastic case of the Vartec series and is designed for installation in electrical distribution devices. Compact dimensions (45×17.8×60.3 mm) allow efficient space utilization in cabinets and control panels. Net weight is only 0.06 kg.
Applications:
The varistor is used in overvoltage protection systems caused by atmospheric discharges or switching surges. The TII protection class defines application in circuits remote from the lightning protection entry point.
