Why Choose the Lovato BFX12C20 Side-Mount Auxiliary Contact Block?
The Lovato BFX12C20 is a side-mount auxiliary contact block with 2NO contacts designed for compatible Lovato BF series contactors. Specifically intended for the BF160…BF400 contactor range, it adds two normally open auxiliary contacts for signalling, interlocking, sequencing and control functions in industrial electrical systems.
Part of the Lovato BFX contactor accessory range, the BFX12C20 features screw terminals and a compact side-mounting arrangement. Its auxiliary contacts are mechanically operated with the associated contactor, allowing the contactor's operating state to be incorporated into PLC inputs, indication circuits, interlocks and other control logic.
The BFX12C20 has a conventional thermal current rating of 10 A, a rated insulation voltage of 690 V and a rated impulse withstand voltage of 6 kV. Its IEC/EN 60947-5-1 A600 / Q600 contact designation makes it a robust accessory for industrial control-panel applications.

Reliable Auxiliary Control for Industrial Contactors
Auxiliary contact blocks extend a contactor's control capabilities by adding contacts that change state mechanically with the main contactor. The Lovato BFX12C20 provides two normally open contacts, allowing two additional circuits to close when the associated contactor is energised.
This arrangement is useful for contactor status feedback, electrical interlocking, control sequencing and signalling. Its side-mounted format integrates directly with compatible Lovato BF contactors while preserving a compact and organised control-panel installation.
Typical Applications
- Contactor operating-status feedback.
- Electrical interlocking circuits.
- Motor starter control systems.
- PLC and industrial automation inputs.
- Control sequencing and signalling circuits.
- Industrial machinery and electrical control panels.
