Circutor OPTIM 3 P&P-52.5-440 Capacitor Battery

The Circutor OPTIM 3 P&P-52.5-440 automatic capacitor bank (reference R3L170) is a highly efficient solution for automatic reactive power compensation in industrial installations with fluctuating loads. Designed to enhance the performance of electrical networks and reduce costs associated with reactive power, this capacitor bank is ideal for compensating rapid power variations in systems with loads that change in seconds.

The OPTIM P&P series by Circutor is characterised by its ease of installation and robustness, making it a perfect choice for industrial installations requiring reliable and durable reactive compensation. The equipment uses contactors for operation, allowing precise control based on demand, and automatically adjusting the compensation according to the system's needs.

This capacitor bank has a capacity of 52.5 kvar at 440 V and is designed to operate in 400 V systems. It consists of three capacitor steps (7.5 + 15 + 30 kvar), allowing for staggered reactive power compensation, optimising the electrical system's performance and avoiding penalties for excessive reactive consumption. This helps reduce contracted power and, consequently, the operational costs of the installation.

The OPTIM 3 P&P-52.5-440 model includes a general circuit breaker, providing integrated protection against overloads and short circuits, ensuring the safety of the equipment and the overall system. Additionally, this equipment offers the option to add a manual or automatic switch at the battery's head, as well as residual current protection, further enhancing safety and facilitating maintenance of the installation.
