BFX101111 - AUX. CONTACT 1NO+1NC+1EM+1LB

Why Choose the LOVATO BFX101111 Auxiliary Contact Block?

The LOVATO BFX101111 is a front centre mounted auxiliary contact block designed for compatible LOVATO BF00, BF09 to BF150 series contactors. It adds additional control contacts for signalling, interlocking, feedback and timing-related control functions within industrial motor control and automation panels.

This accessory provides a 4-pole auxiliary contact arrangement consisting of 1 normally open contact, 1 normally closed contact, 1 early make contact and 1 late break contact. This makes it especially useful where contactor status, sequence control or make-before/break-after auxiliary operation is required.

The BFX101111 features screw terminals for secure wiring and is rated for demanding industrial control circuits, with a 690 V rated insulation voltage, 6 kV impulse withstand voltage and 10 A conventional thermal current. Its mirror and mechanically linked contact functions support dependable auxiliary feedback when used as part of a correctly designed control system.

Reliable Auxiliary Control for Industrial Contactors

Auxiliary contact blocks such as the LOVATO BFX101111 allow contactors to provide additional low-current signalling contacts alongside the main power switching function. These contacts are commonly used for PLC feedback, pilot light indication, electrical interlocking and control circuit sequencing.

The inclusion of early make and late break contacts makes this model useful where auxiliary signals must change state slightly before or after the main contactor movement. This can support more refined control logic in motor starter assemblies, changeover systems and machine control panels.

Typical Applications

• Industrial motor starter panels.
• Contactor feedback and status signalling.
• PLC input monitoring from contactor assemblies.
• Electrical interlocking between contactors.
• Sequence control circuits requiring early make or late break operation.
• Machine building and automation control panels.
• Maintenance and upgrade of LOVATO BF series contactor installations.
