Protective compensation chokes
Three-phase protective compensation reactors for capacitors
The three-phase protective choke limits the higher harmonic currents on the capacitors, which are used for reactive power compensation.
Protective compensation chokes meet the requirements of STN EN 60076-6.
Basic characteristic:
- input voltage 3x400V 50Hz
- thermal insulation T40/F
- protection IP00
- protection class I
- built-in bimetallic heat sensor 125°C /250V-1.5A/
