Bloque de contacto auxiliar ABB CA4-10 1SBN010110R1010

When a contactor or relay needs additional signaling or control circuits, the ABB CA4-10 auxiliary contact block provides a reliable way to expand functionality without replacing the entire device. This front-mount block adds one normally open (NO) contact, enabling status indication, interlocking, or sequencing in industrial control panels.

Who is it for

Panel builders, maintenance technicians, and automation engineers who use ABB contactors and need extra auxiliary contacts for control logic, pilot lights, or PLC inputs. It is suitable for new installations and retrofits where space is limited and reliable switching is required.

Main features

• One normally open (NO) auxiliary contact
• Front mounting for quick installation on compatible ABB contactors
• Compact design saves space in control cabinets
• Model CA4-10, part number 1SBN010110R1010

Tips

Verify compatibility with your ABB contactor series before ordering. The block mounts on the front of the contactor and can be added or replaced without removing the main device. For applications requiring a normally closed (NC) contact, consider the CA4-01 variant.
