Capacitor Switching

Capacitor Duty Contactors

P2 Power Capacitor Duty Contactors are designed specifically for reliable switching of capacitor banks used in power factor correction systems. Capacitor energization can produce significant transient inrush currents, which may place additional stress on conventional switching devices.

P2 Power capacitor duty contactors incorporate pre-switching damping resistors to help control the initial inrush current before the main contacts establish the electrical connection. This controlled switching approach helps reduce electrical stress on the capacitor bank and associated components.

The contactors are suitable for integration into APFC panels, capacitor banks, and reactive power compensation systems.

Key Features
Benefits

Reduced Inrush Current

The integrated damping arrangement helps limit the transient current generated when a capacitor stage is energized, reducing stress on the switching and compensation equipment.

Improved Capacitor Life

Controlled switching can reduce electrical stress on capacitor elements, helping support longer service life when operated within specified conditions.

Lower Operating Losses

The contactor design is optimized for low losses during normal energized operation, supporting efficient APFC system performance.

Reliable Capacitor-Bank Switching

Designed for capacitor-duty applications, these contactors provide dependable switching of individual or multiple capacitor stages in automatic power factor correction systems.
