LOVATO Electric BFX1004 Front-Mount Auxiliary Contact Block 4NC for BF09-BF150 Contactors

The LOVATO Electric BFX1004 is a high-quality front-mount auxiliary contact block engineered specifically for integration with the BF09 to BF150 series contactors. This compact module provides four normally closed (NC) contacts, allowing for the expansion of control circuits and the implementation of complex switching logic within industrial electrical systems. By attaching directly to the front of the main contactor, it offers a space-saving solution for monitoring and interlocking applications.

Advantages

This auxiliary contact block is designed for seamless compatibility and reliable performance in demanding industrial environments. Its front-mounting design simplifies installation and maintenance, as it does not require additional side space on the DIN rail. The robust construction ensures consistent signal transmission, which is critical for maintaining the integrity of control loops and safety interlocking systems in motor control centers and automated machinery.

Suitable for

• Industrial automation systems
• Motor control and protection circuits
• Electrical interlocking applications
• Feedback signaling for control panels

This component is not suitable for applications requiring normally open (NO) contacts, as this specific model is configured exclusively with four normally closed (NC) contacts. It is also not compatible with contactor series outside of the specified BF09 to BF150 range.

Key specifications

• Configuration: 4 normally closed (NC) contacts
• Mounting type: Front-mount
• Compatibility: BF09 to BF150 series contactors
• Function: Auxiliary switching and feedback

To install the BFX1004, ensure that the main contactor is disconnected from the power supply. Align the contact block with the front mounting interface of the compatible BF series contactor and press firmly until it clicks into place. Once secured, verify that the mechanical linkage is functioning correctly before reconnecting the power and testing the control circuit logic.

What to consider before purchase

• Verify that your contactor model falls within the BF09 to BF150 range.
• Confirm that your control logic requires four normally closed (NC) contacts.
• Ensure there is sufficient physical clearance in your enclosure for front-mounted accessories.

For optimal reliability, periodically inspect the contact block terminals for tightness and ensure the environment is free from excessive dust or moisture that could affect electrical conductivity.
