Lovato BFX3371 is a rigid changeover connection kit for four-pole BF40T4, BF50T4, BF65T4 and BF80T4 contactors used with BFX5300 or BFX5301 mechanical interlocks in industrial power-transfer assemblies.

The Lovato BFX3371 is a purpose-designed rigid connecting kit for changeover contactor assemblies using compatible four-pole Lovato BF series contactors. It provides the rigid electrical connections required to construct a coordinated changeover assembly, simplifying panel wiring and helping create a compact, professional installation.
The BFX3371 is designed for four-pole BF40T4, BF50T4, BF65T4 and BF80T4 contactors used together with a Lovato BFX5300 or BFX5301 mechanical interlock. This combination enables two contactors to be mechanically interlocked in a changeover arrangement, helping prevent simultaneous closure of the two switching devices.
As a genuine Lovato BF-series accessory, the BFX3371 eliminates the need to fabricate individual changeover links and provides a coordinated connection solution for industrial switchboards and transfer systems. The kit is supplied as one complete accessory set, has a listed weight of 218 g and is suitable for applications including mains-generator transfer, alternative-source switching and industrial power distribution.
Contactor-based changeover systems use two contactors to select between separate electrical power sources while supplying a common load. The Lovato BFX3371 provides the rigid connections required for compatible four-pole BF contactors, supporting an organised changeover arrangement without requiring panel builders to fabricate individual power links.
When combined with a compatible BFX5300 or BFX5301 mechanical interlock, the BFX3371 forms part of a coordinated Lovato changeover solution. This arrangement is particularly useful in mains-generator transfer, standby-power and alternative-source systems where mechanical interlocking between the two contactors is required.
