ABB CA4-01 is a high-quality, front-mounted auxiliary contact block designed for the ABB AF contactor range. Featuring 1 Normally Closed (1NC) contact, this component is critical for creating electrical interlocks between two contactors (such as in Star-Delta or Forward-Reverse starters) and providing status feedback to control systems.

Key Features:

Snap-On Mounting: Attaches instantly to the front of the contactor without tools, ensuring a secure and vibration-proof connection.

Safety Interlocking: The 1NC configuration is the industry standard for preventing two contactors from closing simultaneously.

Broad Compatibility: Fully compatible with the AF09 through AF96 series, as well as the larger AF116 to AF370 models.

Industrial Durability: Built to withstand high-frequency switching cycles in demanding industrial environments.
