Paktron Quencharc Series (Q/QRL)
RC snubber networks for arc suppression, relay contact protection and dv/dt suppression, 125-660 VAC; QRL is the UL/CSA version.
Description
Paktron's Quencharc is an energy-efficient RC snubber network designed for arc suppression and transient control. It is used for relay contact protection, dv/dt suppression on thyristors and triacs, noise reduction on controllers and drivers, and EMI/RFI reduction. The RC network suppresses the transient voltage that appears when contacts open, helping prevent arcing while also limiting in rush current when contacts close.
Key features
- Type: RC snubber network for arc suppression, non-polarized
- Grade: Industrial / Control / UL/CSA-recognized option available
- Dielectric/Construction: Quencharc is an RC suppression network that combines a metallized polyester capacitor with an integrated series resistor in a UL94V-0 flame-retardant epoxy-coated assembly.
- Rated Voltage: 125 VAC to 660 VAC
- Capacitance: 0.1 μF to 1.0 μF
- Sizes: The series includes several package sizes depending on capacitance/voltage/type
- Operating Temp: -55 °C to +85°C
Applications
- Relay contact protection
- Dv/dt suppression on thyristors and triacs
- Noise reduction on controllers and drivers
- EMI/RFI reduction
- Across-the-line suppression with QRL UL/CSA-recognized versions
