Reliable Switching for Industrial Control Panels

Contactors such as the Lovato BF80T2E024 allow electrical loads to be switched remotely from a control circuit. When the 20...48 V AC/DC electronic coil is energised, the main contacts change state to switch connected circuits within the contactor’s rated utilisation category.

The 2NO + 2NC four-pole arrangement is useful where both normally open and normally closed switching functions are required in one device, such as interlocking, changeover logic, load isolation and multi-circuit control. Its wide-range AC/DC coil helps simplify panel design and spare part selection where compatible AC and DC control supplies may be used across different machines or installations.

Typical Applications

• Industrial control panels and machine cabinets.
• Four-pole AC load switching and power distribution circuits.
• Motor control and machinery switching applications.
• HVAC, refrigeration and ventilation equipment.
• Pumps, fans, compressors and conveyors.
• Production machinery and OEM automation systems.
• AC-1 resistive load switching up to 115 A at 40 °C.
• Applications requiring combined normally open and normally closed power contact switching.

Trusted by Panel Builders Worldwide

Lovato BF contactors are widely used by panel builders, automation engineers and maintenance teams who need reliable switching performance, flexible AC/DC coil control and durable industrial construction.
