LOVATO Electric BFK1810A230 Capacitor Duty Contactor 3P 15kvar 230V AC 1NO

The LOVATO Electric BFK1810A230 is a high-performance 3-pole capacitor duty contactor engineered specifically for the reliable switching of power factor correction capacitor banks. This device is designed to manage the significant inrush currents that occur during the connection of capacitive loads, protecting the electrical system and ensuring the longevity of the capacitors. With a rating of 15kvar at 230V AC and a 230V AC coil, it provides a robust solution for industrial power management.

Advantages

This contactor offers superior durability by utilizing specialized contacts that mitigate the effects of high peak currents during capacitor energization. By reducing contact welding and electrical stress, the unit ensures consistent performance and minimizes maintenance requirements in demanding industrial environments. Its compact design allows for efficient integration into power factor correction panels, while the inclusion of an auxiliary contact facilitates seamless monitoring and control within complex electrical architectures.

Suitable for

• Power factor correction capacitor banks
• Industrial electrical distribution systems
• Reactive power compensation panels
• Capacitive load switching applications

When it may not be suitable

This contactor is specifically optimized for capacitive loads and should not be used for standard inductive motor control or resistive heating applications where different contact materials and arc suppression methods are required. It is not intended for use in circuits exceeding its rated voltage or reactive power capacity.

Key specifications

• Number of poles: 3
• Rated power: 15kvar at 230V AC
• Coil voltage: 230V AC
• Auxiliary contacts: 1 normally open (1NO)
• Application: Capacitor duty switching

How to use

Installation should be performed by qualified electrical personnel in accordance with local safety regulations. The contactor is designed for mounting on standard DIN rails or via screw fixing within an electrical enclosure. Ensure that the control circuit voltage matches the 230V AC coil rating before connection. Wiring should be sized appropriately for the load current to prevent overheating, and all terminal screws must be tightened to the manufacturer's specified torque settings to ensure a secure electrical connection.

What to consider before purchase

• Verify that the reactive power (kvar) of your capacitor bank does not exceed the 15kvar rating.
• Ensure the control voltage of your system matches the 230V AC coil specification.
• Check available space in the electrical panel for mounting.
• Confirm the compatibility of the auxiliary contact with your monitoring system.

Usage recommendations: Regularly inspect the terminal connections for tightness and check for signs of excessive heat or discoloration during routine maintenance intervals to ensure long-term operational reliability.
