The Lovato BFX5504 is a purpose-designed vertical mechanical interlock for Lovato BF160…BF400 contactors. It is intended for installations where two compatible contactors are mounted one above the other and provides an adjustable interaxis range of 345–385 mm.
Part of the Lovato BFX contactor accessory range, the BFX5504 mechanically interlocks the associated contactors so that they cannot both be closed simultaneously. This provides an important physical interlocking function in reversing, changeover and other power-control circuits where the two contactor states must remain mutually exclusive.
The BFX5504 supports both 3-pole and 4-pole BF160…BF400 contactors within the manufacturer's specified mounting arrangements. Its vertical configuration is particularly useful for control-panel layouts where the contactors need to be stacked rather than installed side by side.
Mechanical interlocking provides a physical safeguard against simultaneous operation of two contactors. When one contactor is closed, the interlock mechanically prevents the opposing contactor from closing, complementing the electrical control logic used within the switching system.
The Lovato BFX5504 is specifically engineered for vertically arranged BF160…BF400 contactors. Its 345–385 mm adjustable interaxis enables the mechanism to accommodate the manufacturer's specified stacked configurations while providing dependable mechanical interlocking for industrial power-control systems.
