Contactors for capacitor switching

• Capacitor switching application leads to very high current peak at capacitor energization
• UAFC..RA contactors are designed with damping resistor to handle current peaks up to 200x In
• Power factor correction panels are using controllers to monitor power factor and control switching of capacitor banks to improve power factor level.
• Capacitor banks are composed of capacitors. They have strong inrush current at energization
• Power factor correction application can have one or more capacitor bank (called steps) controlled by contactors
• Contactor need to be able to handle the strong inrush current.

Product benefits

• Widest contactor range on the market with 2 levels of peak capability
• Common AF platform – Compatible accessory range
• Space saving with a compact design
