Auxiliary contact CAL4-11 1SBN010120R1011

Auxiliary contact – reliable extension of functionality

This auxiliary contact, catalog number 1SBN010120R1011 (CAL4-11), is a key element for expanding control systems. It is used to add additional auxiliary contacts to switches and contactors, allowing for the implementation of more complex logical and signaling functions in the installation. Side mounting simplifies integration with existing systems, and screw connection ensures secure and durable electrical connections.

Construction and application

The CAL4-11 contact is designed for side mounting, meaning it is mounted directly to the housing of the switch or contactor. It has one normally closed (NC) contact and one normally open (NO) contact, providing flexibility in configuring control circuits. The rated operating current of up to 4A at AC-15/230V makes it suitable for controlling circuits with lower power. This is an ideal solution where additional feedback on the device status is needed or it is necessary to control other elements of the installation.

Advantages and benefits

• Versatility: the ability to add additional auxiliary contacts increases the functionality of existing devices.
• Secure connections: screw connection guarantees stable and reliable electrical connections, minimizing the risk of failure.
• Easy installation: side mounting simplifies installation and integration with existing systems.
• Universality: suitable for use in various industrial and construction applications.
• Compatibility with standards: compatible with a wide range of ABB switches and contactors.
