FAQs
The CA4X-20 auxiliary contact block (2 NO) is designed for front mounting on a wide range of ABB AFC contactors from AFC09 through AFC96 and NFC relays. It uses screw terminals for secure terminations and is compatible with both rigid and flexible conductors. When sizing wiring and mounting, ensure the block aligns with the AFC contactor baseline and that the enclosure offers IP20 protection. This simplifies retrofits and new builds by providing a universal, plug-in style accessory that reduces wiring errors during assembly.
CA4X-20 provides two normally open auxiliary contacts (2 NO) in a 2P configuration, rated for auxiliary circuits up to 690 V and 50/60 Hz. It supports I th up to 10 A and I e values across a broad voltage range, with a standard short-time withstand of 140 A for 0.1 s. Its insulation voltage is 690 V, Uimp is 6 kV, and it operates within typical AC-15 and DC-13 conditions. This makes it suitable for status signaling and interlocking in many industrial applications.
Choosing CA4X-20 brings clear wiring paths and enhanced diagnostics due to dedicated NO contacts for signal feedback. The front-mounted design minimizes wiring length inside the panel and the screw terminals ensure robust terminations. The block’s compact dimensions preserve enclosure space, while the 2P, 2 NO configuration supports straightforward interlocks and status indication, translating to faster commissioning and easier troubleshooting during maintenance windows.
CA4X-20 carries multiple compliance marks including UL 60947-5-1, IEC/EN 60947-1, IEC/EN 60947-5-1, and GB14048.5, with CE declarations supporting global deployment. These certifications ensure safety, reliability, and interoperability with global control equipment. For regulated industries, this means you can document conformity quickly, reduce risk during audits, and simplify supplier qualification for electrical protection and circuit control components.
The auxiliary block reduces wiring complexity and shortens panel assembly time, which lowers labor costs during commissioning. Its robust screw-terminal connections resist loosening in vibration-heavy environments, reducing ongoing maintenance visits. The standardized footprint and compatibility across AFC09–AFC96 simplify spare parts management and stock, delivering faster repair cycles and improved machine uptime in high-demand automation settings.
