ABB CA4-10 Auxiliary Contact Block for AF Series Contactors

The ABB CA4-10 is a side-mounted auxiliary contact block designed for use with ABB AF series contactors. This compact add-on module provides one normally open (1 N/O) auxiliary contact, allowing you to expand the control and monitoring capabilities of your contactor installation.

Key Features:

• One normally open (1 N/O) auxiliary contact configuration
• Side-mounted design for easy installation on AF series contactors
• Rated for control circuit switching and signaling applications
• Compact footprint conserves panel space
• Reliable snap-on mounting mechanism
• Compatible with AF09 through AF96 contactor frames

Auxiliary contact blocks like the CA4-10 are essential for creating interlocking circuits, providing remote indication, or controlling additional equipment in industrial motor control and automation applications. The normally open contact closes when the contactor coil is energized, making it ideal for pilot lights, PLC inputs, or downstream control circuits.
