Reliable Auxiliary Switching for Control Circuits

Auxiliary contact blocks such as the ABB CA3-01 are used to provide additional signalling and control functions on contactors and contactor relays. They allow electrical systems to monitor contactor status, create electrical interlocks or switch auxiliary circuits independently from the main power contacts.

The ABB 1SBN011010T1001 is designed for simple front mounting and secure connection, helping panel builders and maintenance engineers add functionality to compatible ABB devices without unnecessary panel complexity. Its normally closed contact configuration is particularly useful for safety interlocks, feedback loops and control logic applications.

Typical Applications

• Industrial motor control panels.
• Auxiliary control and signalling circuits.
• Electrical interlocking systems.
• Contactor status feedback circuits.
• Machine automation and process control panels.
• Panel building, maintenance and retrofit applications.

Trusted by Panel Builders and Automation Engineers

ABB auxiliary contact blocks are widely used by panel builders, maintenance engineers and automation professionals to expand contactor functionality and support reliable industrial control circuit operation.
