Description

The ABB CA4-10 is a side-mount auxiliary contact block providing one normally open (N.O.) contact for use with ABB A-Line contactors in the A9 to A110 product range. Rated at 10 A / 690 V AC and compliant with IEC 60947-5-1, the CA4-10 is designed to add N.O. signalling or control contacts to contactors that require additional outputs beyond those built into the contactor body. The block fits directly onto the side of compatible contactors with a snap-on mounting mechanism that requires no tools, enabling rapid assembly and modification during panel building.

The N.O. contact configuration of the CA4-10 makes it ideal for run indication lamps, PLC feedback inputs, interlock signalling, and remote monitoring applications within motor control circuits. Its screw terminals accept both flexible and solid conductors and are rated for reliable long-term connection security under the vibration and thermal conditions typically encountered in industrial control panel environments. The compact, low-profile housing minimises the impact on overall contactor assembly width, maintaining space-efficient control panel layouts.

The CA4-10 is widely used by panel builders and electrical contractors across the full range of ABB A-Line contactor applications, including direct-on-line, reversing, star-delta, and soft-start motor control configurations. It is often used in combination with CA4-01 N.C. blocks to provide the precise combination of auxiliary contact outputs required by specific control circuit designs. As an authentic ABB accessory, it ensures compatibility and co-ordination with the A-Line contactor range, supporting the reliable long-term performance of motor control installations in industrial, commercial, and infrastructure applications.
