Lovato Electric BFK0910A230 3-Pole Capacitor Contactor, 7.5kvar, 230V AC, 1NO

The Lovato Electric BFK0910A230 is a high-performance 3-pole capacitor contactor engineered specifically for the reliable switching of power factor correction capacitor banks. This device is built to handle the demanding electrical requirements of industrial environments, providing a robust solution for managing capacitive loads. With a rating of 7.5kvar at 400V and a 230V AC operating coil, it ensures precise control and long-term operational stability in electrical distribution systems.

Advantages

This contactor is specifically designed to mitigate the high inrush currents that typically occur when switching capacitor banks, which helps to extend the lifespan of both the capacitors and the contactor itself. Its specialized construction reduces contact wear and prevents welding, ensuring consistent performance over many switching cycles. The inclusion of a built-in auxiliary contact allows for seamless integration into existing control and monitoring circuits, enhancing the overall safety and functionality of the electrical installation.

Suitable for

• Power factor correction systems
• Industrial capacitor banks
• Reactive power compensation panels
• Electrical distribution networks requiring capacitive load switching

When it may not be suitable

This device is not intended for general-purpose motor starting or switching highly inductive loads, as its internal design is optimized specifically for capacitive currents. It should not be used in applications where the required reactive power exceeds the 7.5kvar rating at 400V.

Key specifications

• Number of poles: 3
• Power rating: 7.5kvar at 400V
• Coil voltage: 230V AC
• Auxiliary contact: 1 Normally Open (NO)
• Application: Capacitor bank switching

How to use

The contactor should be installed within a suitable electrical enclosure by a qualified professional. Ensure that the coil voltage matches your control circuit supply before connection. The power terminals should be wired to the capacitor bank circuit, while the auxiliary contact can be integrated into the control logic for status monitoring or interlocking purposes. Always verify that all connections are tightened to the manufacturer's specified torque settings to prevent overheating.

What to consider before purchase

• Verify the total reactive power of your capacitor bank matches the 7.5kvar rating.
• Confirm that your control circuit provides a 230V AC signal for the coil.
• Ensure the installation environment meets the required IP rating and temperature conditions.

Usage recommendations

Regularly inspect the contactor for signs of wear or overheating, especially if the switching frequency is high. Ensure that the capacitor bank is properly discharged before performing maintenance on the electrical circuit.
