Lovato Electric BFX5001 Mechanical Interlock with 2NC Auxiliary Contact for BF09-BF38 Contactors

The Lovato Electric BFX5001 is a high-quality mechanical interlock device engineered specifically for use with BF09 to BF38 series contactors. This essential component ensures operational safety in industrial control systems by physically preventing the simultaneous activation of two contactors, which is critical for preventing short circuits in motor reversing or changeover configurations. The unit comes equipped with an integrated 2NC auxiliary contact, providing reliable electrical feedback regarding the status of the interlock mechanism.

Advantages

The primary advantage of the BFX5001 is its robust mechanical design that guarantees a high level of safety and reliability in demanding electrical environments. By integrating the mechanical interlock with a 2NC auxiliary contact, the device simplifies the assembly process and reduces the need for additional wiring or external components. Its compatibility with the BF09-BF38 contactor range makes it a versatile solution for standardizing control panels and ensuring consistent performance across various motor control applications.

Suitable for

• Motor reversing circuits
• Power changeover applications
• Industrial automation control panels
• Safety-critical switching systems

When it may not be suitable

This device is specifically designed for the Lovato BF09 to BF38 contactor series and is not compatible with other contactor models or brands. It should not be used in applications requiring different auxiliary contact configurations, such as NO (normally open) contacts, as the integrated 2NC contact is fixed.

Key specifications

• Compatibility: Lovato BF09 to BF38 contactors
• Integrated auxiliary contact: 2NC (normally closed)
• Function: Mechanical interlocking

How to use

To install the BFX5001, ensure that the power supply to the contactors is completely disconnected. Align the mechanical interlock with the mounting points on the front or side of the contactors as specified in the installation manual. Secure the device firmly to ensure the mechanical linkage is correctly engaged. Once installed, connect the 2NC auxiliary contact terminals to your control circuit to monitor the interlock status. Perform a manual test to verify that the mechanical linkage prevents both contactors from closing at the same time before applying power.

What to consider before purchase

• Verify that your contactor model falls within the BF09 to BF38 range
• Confirm that your control logic requires a 2NC auxiliary contact configuration
• Check available space in your control cabinet for the additional depth or width required by the interlock

Usage recommendations

Always verify the mechanical operation of the interlock before energizing the system to ensure that the physical lockout is functioning correctly and that the auxiliary contacts provide the expected signal to your PLC or control relay.
