BFX5003 - FRONT MOUNT MECHANICAL INTERLOCK

Why Choose the LOVATO BFX5003 Mechanical Interlock?

The LOVATO BFX5003 is a genuine LOVATO Electric front-mounted mechanical interlock designed for compatible LOVATO BF00, BF09 to BF38 series contactors. It is used to mechanically prevent two contactors from closing at the same time, making it an important accessory for reversing, changeover and interlocked control circuits.

This accessory is particularly useful in motor control panels and automation systems where two contactors operate in opposition, such as forward and reverse motor starter arrangements. By physically linking the contactor mechanisms, the BFX5003 provides an additional layer of mechanical protection alongside the electrical interlocking designed into the control circuit.

With a compact front mount design, the BFX5003 is straightforward to install on suitable LOVATO BF contactors. It is supplied as a lightweight accessory for professional panel builders, OEM machine builders and maintenance engineers working with LOVATO BF series contactor assemblies.

Mechanical Interlocking for Safer Contactor Coordination

Mechanical interlocks such as the LOVATO BFX5003 are used where two contactors must not be energised at the same time. In reversing motor starters, for example, one contactor may control forward rotation while the other controls reverse rotation. Mechanical interlocking helps prevent both contactors from closing together, reducing the risk of incorrect switching conditions.

The BFX5003 is a front-mounted interlock accessory, meaning it fits directly to the front of compatible LOVATO BF contactors. When used with correct electrical interlocking and control circuit design, it supports reliable contactor coordination in industrial panels, machinery systems and OEM automation assemblies.

Typical Applications

• Forward and reverse motor starter assemblies.
• Changeover contactor arrangements.
• Industrial motor control panels.
• Machine automation and OEM control systems.
• Electrical interlocking between paired contactors.
• Pump, fan and conveyor control panels.
• Maintenance and replacement of LOVATO BF series contactor accessories.
