A Revolutionary Solution for a Changing Industry
- Closing resistors provide the most reliable and consistently repeatable voltage and current transient suppression available in the market.
- Designed and tested for restrike-free performance
- Makes and breaks circuit in SF6 gas rather than in air
- Simple, cost effective, mechanical design provides repeatability
- Eliminates the need for inrush reactors
- Long Life (10,000 operations)
- Availability of multiple resistor sizes allows performance optimization
- Each unit is completely assembled and tested at the factory with only the disassembly required to accommodate shipment restrictions being performed
- Gas monitoring provided on all designs
- Integrated capacitor control available for some ratings – consult factory
