Auxiliary contact CA4-01 1SBN010110R1001

Auxiliary contact – expansion of contactor functionality

The CA4-01 auxiliary contact is a reliable accessory that expands the capabilities of contactors in control and protection circuits. Front-mounted, it provides a flexible solution for installers and end-users who need an additional auxiliary contact in the circuit. The device is compatible with a wide range of ABB AF09 to AF96 series contactors and NF relays, making it a universal element in many installations.

Construction and application

CA4-01 has one normally closed contact (1NC), which means that under normal conditions the circuit is closed and opens when a control signal occurs. Screw terminals ensure a secure and durable connection of wires, minimizing the risk of errors during installation and operation. Front mounting makes it easy to integrate the contact with existing contactors without the need to disassemble the entire installation. This makes replacing or adding an auxiliary contact quick and easy.

Advantages and benefits

• Versatility: Compatibility with various ABB contactor series (AF09-AF96 and NF) allows it to be used in many industrial and construction applications.
• Reliability: Made of high-quality materials, it ensures long-lasting and trouble-free operation even in harsh environmental conditions.
• Easy installation: Front mounting and screw terminals facilitate installation and maintenance, saving time and labor costs.
• Safety: Provides effective signaling of the circuit's operating status, which increases the safety of using the electrical installation.
• Secure connections: Screw terminals guarantee a stable connection of wires, minimizing the risk of circuit interruptions.
• Designed for auxiliary circuits: Suitable for operation with voltages from 24 V to 690 V AC, it allows its use in various control applications.
• Compliance with standards: Meets industrial standards for operating currents (4 A at 230 V AC in category AC-15), which guarantees its safety and efficiency.

This auxiliary contact is an ideal solution for electricians and automation engineers looking for a reliable and easy-to-install element that expands the functionality of contactors in their projects. It allows precise monitoring of the circuit status and a quick response to any failures or irregularities.
