BFX3271 Lovato CHANGE OVER CONNECTION KIT BF26-38T4

Why Choose the Lovato BFX3271 Changeover Connection Kit?

The Lovato BFX3271 is a rigid connecting kit for changeover contactor assemblies, specifically designed for Lovato BF26…T4 and BF38…T4 four-pole contactors. It provides the predefined power connections required when assembling a compact four-pole changeover arrangement, reducing the need to fabricate and route individual flexible conductors between the contactors.

The BFX3271 is designed for use with two compatible four-pole BF contactors combined with a Lovato BFX5000 or BFX5001 mechanical interlock. The resulting arrangement is suitable for changeover applications where two supplies are switched to a common load while the mechanical interlock prevents simultaneous operation of the two contactors.

For IEC applications, the BFX3271 has a conventional free-air thermal current rating of 55 A at up to 40 °C. The kit is also cULus certified and has a UL rated operational voltage of 600 V AC, providing a manufacturer-engineered connection solution for industrial changeover panels, transfer systems and power-control assemblies.

Efficient Changeover Connections for Industrial Automation

The Lovato BFX3271 simplifies the construction of a four-pole changeover assembly by providing rigid, purpose-designed electrical connections between compatible BF26…T4 or BF38…T4 contactors. Compared with individually measuring, cutting and routing flexible power conductors, the preformed kit can reduce assembly work while helping maintain a neat and consistent panel layout.

When used with a BFX5000 or BFX5001 mechanical interlock, two compatible contactors can form a mechanically interlocked changeover arrangement. This type of assembly is commonly used where a load must be transferred between two electrical sources, including automatic transfer, generator and standby-power control systems.

Typical Applications

• Four-pole changeover contactor assemblies.
• Mains and generator changeover systems.
• Automatic transfer switching assemblies.
• Standby and emergency power systems.
• Industrial switchboards and distribution panels.
• Generator control and transfer panels.
• Building services power-control systems.
• OEM industrial automation and power-switching equipment.
