Paktron Quencharc Series (Q/QRL)

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
