Capacitor Duty Contactors
Capacitor Duty Contactors Supplier
Capacitor Duty Contactors
Use of capacitor duty contactor enhance the life of the capacitors also nlimits the system transients thus improving power quality. Contactors have additional auxiliary contacts with current limiting resistors in series with it.
Product Description
Capacitor Duty Contactors are designed in particular for capacitor switching applications. As capacitor switching is associated with high inrush current, the contactors are equipped with dampening resistors that reduce the inrush current to a safe level. The contactors are utilised in APFC panels to swap power capacitors based on the amount of reactive power correction needed. The capacitor duty contacts are of the block type construction. – Control circuit: AC-powered and appropriate for 50/60Hz frequencies – Accessories: A variety of accessories are available. Daga Switchgears & Electricals Pvt. Ltd. is a trusted of high-performance Capacitor Duty Contactors supplier across Kolkata, West Bengal, Odisha, Bihar, Jharkhand, Chhattisgarh, and Assam. Our solutions are designed to enhance power factor correction systems with reliable and efficient performance.
What are Capacitor Duty Contactors?
Capacitor Duty Contactors are specialized devices designed for switching capacitor banks in power factor correction (PFC) applications. These contactors are equipped with damping resistors to handle high inrush currents and reduce transient disturbances.
