Why Choose the Lovato BFX5503 Vertical Mechanical Interlock?
The Lovato BFX5503 is a purpose-designed vertical mechanical interlock for Lovato BF160…BF400 contactors. It is engineered for installations where two compatible contactors are mounted one above the other and provides an interaxis adjustment range of 305–345 mm.
Part of the Lovato BFX contactor accessory range, the BFX5503 mechanically prevents two associated contactors from being closed simultaneously. This makes it particularly useful in reversing, changeover and other interlocked contactor arrangements where simultaneous operation could result in an incorrect or unsafe switching condition.
The vertical arrangement enables compatible BF contactors to be installed in a stacked configuration rather than side by side. With its 305–345 mm centre-to-centre mounting range and compatibility across the BF160…BF400 family, the BFX5503 provides a dedicated mechanical interlocking solution for larger Lovato contactor assemblies.
Key Advantages
- Purpose-designed mechanical interlock for BF160…BF400 contactors.
- Supports one-above-the-other vertical contactor mounting.
- 305–345 mm interaxis range for compatible installations.
- Mechanically prevents both interconnected contactors from closing simultaneously.
- Ideal for reversing, changeover and mutually interlocked switching arrangements.
- Dedicated Lovato accessory provides coordinated integration with compatible BF contactors.
Key Features
- Lovato BFX mechanical interlock accessory.
- Vertical mounting configuration.
- Designed for contactors mounted one on top of the other.
- 305–345 mm interaxis.

Reliable Mechanical Interlocking for Contactor Assemblies
Mechanical interlocking provides a physical means of preventing two contactors from closing at the same time. Unlike electrical interlocking alone, the mechanism acts directly on the contactor arrangement, providing an additional layer of operational control in circuits where mutually exclusive switching is required.
The Lovato BFX5503 is specifically configured for vertically arranged BF160…BF400 contactors. Its 305–345 mm interaxis range enables the paired contactors to be positioned one above the other while maintaining the mechanical connection required for reliable interlocking.
Typical Applications
- Forward/reverse motor starter assemblies.
- Power-source changeover contactor systems.
- Mutually interlocked power-switching circuits.
- Industrial motor-control panels.
- Machinery and automation control systems.
- OEM electrical and power-control assemblies.
