BFX77125 Lovato surgesurpressors 48 to 125 VAC / DC Varistor

Why Choose the Lovato Electric BFX77125 Surge Suppressor?

The Lovato Electric BFX77125 is a compact quick-connect surge suppressor designed for use with Lovato BF series AC contactors. Engineered to protect industrial control circuits from damaging voltage transients generated during switching operations, this accessory improves electrical reliability and reduces electromagnetic interference in automation systems.

Using an integrated varistor suppression circuit, the BFX77125 absorbs high-energy voltage spikes produced when contactor coils are de-energised. This helps protect PLC outputs, relay contacts and sensitive automation electronics while extending the service life of switching equipment.

Designed specifically for BF00A and BF09 to BF150A contactors, the BFX77125 supports 48-125VAC/DC coil voltages and features a fast quick-connect installation format for efficient integration into industrial control panels and OEM machinery.

Reliable Coil Protection for Industrial Automation Systems

Surge suppressors are widely used in industrial motor control systems to minimise voltage spikes generated by contactor coils during switching operations. Without suppression, these transient voltages can interfere with nearby electronics, damage relay contacts and reduce the lifespan of automation equipment.

The Lovato BFX77125 uses integrated varistor technology to absorb excess voltage energy and reduce electromagnetic interference within industrial control panels. Its compact quick-connect design allows rapid installation while improving the reliability and operational stability of automation and motor control systems.

Typical Applications

• Industrial motor starter systems.
• PLC-controlled automation panels.
• Machine automation and OEM equipment.
• Electrical switchboards and control cabinets.
• Industrial process control systems.
• Contactor coil EMC and surge protection.
