6 FAQs about [Chicago Capacitor Contactor]
What is a capacitor duty contactor?
As capacitor switching is associated with high inrush current, the Contactors are provided with damping resistors which limit the value of inrush current to a safe value. C&S Electric offers Capacitor Duty Contactor designed for capacitor switching applications. It enhances equipment life and optimizes solution cost.
Which contactors are suited for capacitor bank switching?
Application The A...and AF...contactors are suited for capacitor bank switching for the peak current and power values in the table below. The capacitors must be discharged (maximum residual voltage at terminals < 50 V)before being re-energized when the contactors are making.
What type of contactor should I use for switching capacitors?
Use K3-..A contactors for switching capacitors that have a series reactor (filter, tuning, detuning, etc.) that reduces transients normally associated with the switching of capacitors. FRAKO Type A contactors (without pre-charge resistors) are rated for the maximum capacitive current (or kVAR).
What is a capacitor contactor with a damping resistor?
Capacitor contactors with damping resistors make use of pre-switching auxiliary contacts. They close before the main contacts and pre-load the capacitor thus avoiding current peak values. This positively influences the life expectancy of the capacitor and the positive impact on the power quality. The values above reflect typical specifications.
How does a capacitor contactor affect power quality?
This has a significant positive influence on the life expectancy of the capacitor and also positively impacts the power quality (by avoiding transients and voltage drops that otherwise may be caused by switching in capacitors). Capacitor contactors are available for PFC systems with or without reactors.
What are frako capacitor switching contactors?
FRAKO capacitor switching contactors are designed for long life, yet they are compact and have low power losses. When switched capacitors do not include series connected reactors, it is very important to use contactors with pre-charge resistors.
