Overview

The ABB Electrification CA4-01K is a front-mounting auxiliary contact block designed for auxiliary and control circuits in standard industrial environments. This model features one normally closed (NC) instantaneous contact, making it ideal for signaling, interlocking, or status indication in motor control applications. The CA4-01K is specifically compatible with ABB AF09 through AF96 contactors and contactor relays with NF configurations, ensuring seamless integration into existing ABB control systems. The CA4-01K utilizes ABB's push-in spring terminal technology, which eliminates the need for traditional screw terminals. This design enables faster, tool-free wiring with secure, vibration-resistant connections that reduce installation time by up to 50% compared to screw-type terminals. Each push-in spring terminal is protected against accidental direct contact, enhancing safety for electricians and maintenance personnel during installation and servicing. Each terminal is clearly marked with its function (N.C. for normally closed), simplifying circuit identification and troubleshooting. The compact front-mounting design allows for direct attachment to specified ABB contactors, eliminating the need for additional mounting hardware. The CA4-01K is manufactured in Germany (DE) and adheres to ABB's stringent quality standards, ensuring reliable performance in demanding industrial environments. Key specifications include: 1 NC instantaneous contact, push-in spring terminals, front-mounting compatibility with AF09-AF96 contactors, and protection against accidental contact. The product is part of ABB's auxiliary contact block series, designed for use in auxiliary circuits and control circuits within standard industrial environments.
