LOVATO Electric BFX1220 Auxiliary Contact Block, 2NC, Side Mount

The LOVATO Electric BFX1220 is a professional-grade auxiliary contact block designed for seamless integration with industrial contactors. This side-mounted component provides two normally closed (NC) contacts, enabling reliable monitoring and feedback of the switching status within electrical control systems. Engineered for durability and precision, it serves as an essential modular addition to control panels, ensuring consistent performance in demanding industrial environments.

Advantages

The primary benefit of the BFX1220 is its robust design which ensures long-term operational reliability in various industrial settings. Its side-mounting configuration allows for efficient space management within control cabinets, facilitating a cleaner and more organized installation. By providing two NC contacts, it offers precise status signaling, which is critical for safety interlocks and automated control sequences. The modular nature of this contact block ensures quick and straightforward installation, reducing downtime during system upgrades or maintenance.

Suitable for

• Industrial automation control panels
• Motor control centers
• Safety interlock systems
• Status monitoring and feedback loops

This auxiliary contact block may not be suitable for applications requiring normally open (NO) contacts, as this specific model is configured exclusively with two normally closed (NC) contacts. It is also not intended for use with contactor series outside of the compatible LOVATO range, as mechanical and electrical compatibility is required for safe operation.

Key specifications

• Contact configuration: 2 Normally Closed (NC)
• Mounting type: Side mount
• Compatibility: Specific LOVATO Electric contactor series
• Application: Industrial control and switching

To install the BFX1220, ensure the main contactor is disconnected from the power supply. Align the auxiliary contact block with the designated side mounting interface on the compatible contactor. Press firmly until the mechanical locking mechanism engages securely. Once attached, connect the control wiring to the terminals according to your electrical schematic, ensuring all connections are tightened to the manufacturer's specified torque settings.

What to consider before purchase

• Verify compatibility with your existing contactor model
• Confirm that the 2NC configuration meets your control circuit requirements
• Ensure sufficient physical space is available on the side of the contactor for mounting

Always verify that the auxiliary contact block is fully seated and that all terminal connections are secure before restoring power to the control circuit. Regularly inspect the contacts for signs of wear or debris to maintain optimal switching performance.
