BFX77048 Lovato surgesurpressors 48VAC / DC Varistor

Why Choose the Lovato Electric BFX77048 Surge Suppressor?

The Lovato Electric BFX77048 is a compact quick-connect surge suppressor designed for use with Lovato BF series AC contactors. Engineered to protect control circuits and contactor coils from voltage transients generated during switching operations, this accessory improves electrical reliability and helps reduce electromagnetic interference within industrial automation systems.

Using an integrated varistor suppression circuit, the BFX77048 limits harmful voltage spikes generated when contactor coils are de-energised. This helps protect PLC outputs, relay contacts and sensitive electronic control equipment while extending the operational life of switching components.

Designed specifically for BF00A to BF150A contactors with coil voltages up to 48VAC/DC, the BFX77048 features a quick-connect installation format that enables fast and reliable fitting directly onto compatible contactors. Its compact industrial design makes it ideal for modern control panels and OEM machinery applications.

Reliable Coil Protection for Industrial Control 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 BFX77048 uses integrated varistor technology to absorb excess voltage energy and reduce electromagnetic interference within industrial control panels. Its compact quick-connect design allows fast installation while helping improve the overall reliability 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.
