Surge arrester MVR
MVR is a surge arrester with metal-oxide (MO) resistors without spark gaps, designed and tested with reference to IEC 60099-4.
It is used for secure protection of medium voltage systems against overvoltages from atmospheric discharges and switching conditions.
Applications
- Power electronics
- High-voltage cable sheath
- Low-voltage motors
- Components of low-voltage secondary equipment
