Specially designed to operate power factor correction capacitors (utilization category AC-6b). Special development to perform specific operations for this type of application.
DescriptionWEG CWM25C, CWM32C, CWM50C and CWM65C contactors were specially designed to operate power factor correction capacitors (utilization category AC-6b). Special development to perform specific operations for this type of application.
Main Features- Low costs
- High reliability
- Small dimensions
- Direct mounting on DIN Rail 35mm or with fixing screws
- Built-in pre-charge resistors
- Technical specifications according to IEC 60914-4 and VDE 0660
- AC coils
During the operation of WEG’s series of contactors for capacitor switching (the CWMC series) the pre-charged resistors with reactive loads allow the reduction of in-rush current peaks, characteristic of this type of application.
After the pre-charge, the main contacts close to allow the flow of operational current.
For reactive powers higher than 15 kVAr (at 220V) and 25 kVAr (at 380/440V), it is recommended to divide the capacitors bank into smaller modules and switch the banks using these special contactors,CWMC25, CWMC32, CWMC50 and CWMC65.
