BFX1040 - AUX. CONTACT 4NO W FRONT CENTRE MOUNTING

Why Choose the LOVATO BFX1040 Auxiliary Contact Block?

The LOVATO BFX1040 is a compact front centre mounted auxiliary contact block designed for compatible LOVATO BF00, BF09 to BF150 series contactors. It provides four additional normally open auxiliary contacts for control, signalling, feedback and automation logic within industrial electrical panels.

This model features a 4 normally open contact arrangement, making it ideal where multiple make contacts are required from a single contactor assembly. The BFX1040 can be used to provide PLC input signals, pilot light indication, holding circuits, permissive signals and auxiliary control functions across motor control and machine automation systems.

With screw terminals, front centre mounting and a robust industrial design, the BFX1040 is straightforward to install and service. It is rated for demanding control circuit applications, with a 690 V rated insulation voltage, 6 kV rated impulse withstand voltage and 10 A conventional thermal current.

Reliable Auxiliary Switching for Contactor Control

Auxiliary contact blocks such as the LOVATO BFX1040 allow a contactor to provide additional low-current switching contacts separate from the main power contacts. These auxiliary contacts are commonly used to confirm contactor operation, send signals to PLC inputs, operate indication circuits and support control relay logic.

The 4NO configuration is useful where several independent normally open auxiliary signals are required from the same contactor. This makes the BFX1040 suitable for motor starter panels, machine control systems and industrial automation assemblies where reliable contactor status and control signalling are essential.

Typical Applications

• Industrial motor starter panels.
• Contactor status feedback and auxiliary signalling.
• PLC input monitoring from contactor assemblies.
• Holding circuits and control relay logic.
• Pilot light and indication circuits.
• Machine control and automation panels.
• Pump, fan and conveyor control systems.
• Maintenance and replacement of LOVATO BF series contactor accessories.
