£43.02
The Lovato BFX5301 is a reliable mechanical interlock accessory designed for Lovato BF series contactors used in industrial motor control and automation applications. It provides a secure mechanical locking function that prevents two contactors from closing simultaneously, making it ideal for reversing starters and changeover switching systems.
Designed for side mounting with two normally closed (2NC) contacts, the BFX5301 combines mechanical interlocking with auxiliary contact functionality to improve safety and control reliability in contactor assemblies. It is compatible with Lovato BF40, BF50, BF65, BF80 and BF94 contactors.
With its compact construction and simple installation method, the Lovato BFX5301 provides an effective solution for industrial panels requiring reliable contactor coordination, especially in motor reversing and transfer applications.
Mechanical interlocks such as the Lovato BFX5301 provide an important protection function in electrical control systems by physically preventing incompatible contactors from operating together. This is essential in applications such as reversing motor starters where two contactors must never be energised at the same time.
The BFX5301 is designed for panel builders, automation engineers and electrical installers requiring dependable accessories for Lovato BF contactors in industrial machinery and control applications.
