Finder 022.73 Auxiliary Contact Block 2NO for 22.74 Contactors

The Finder 022.73 auxiliary contact block is a precision-engineered component designed to extend the functionality of Finder 22.74 series modular contactors. Featuring 2NO (normally open) contacts, this block allows for seamless integration into complex control circuits, providing reliable feedback and signaling capabilities for industrial and building automation applications. Its modular design ensures a secure and straightforward connection to the main contactor unit, maintaining the high standards of performance and durability expected from Finder electrical components.

Advantages

This auxiliary contact block offers significant flexibility by enabling the monitoring and control of secondary circuits directly through the main contactor. By adding 2NO contacts, users can easily implement status signaling, interlocking, or additional control logic without the need for separate relay units. The compact design preserves space within electrical enclosures, while the robust construction ensures long-term operational reliability in demanding environments. Its compatibility with the 22.74 series ensures a perfect fit and consistent electrical performance across the entire system.

Suitable for

• Industrial automation control systems
• Building management and lighting control
• HVAC system integration
• Signal transmission for monitoring equipment
• Electrical interlocking circuits

This component is not suitable for use with contactor series other than the specified 22.74 range. It is also not intended for high-power switching applications, as it is designed exclusively for auxiliary control signals and low-current monitoring tasks.

Key specifications

• Contact configuration: 2NO (Normally Open)
• Compatibility: Finder 22.74 series contactors
• Mounting type: Modular side-mount
• Application: Control and signal circuits

To use the Finder 022.73, ensure the main contactor is disconnected from the power supply before installation. Align the auxiliary block with the designated mounting interface on the side of the 22.74 contactor and press firmly until it clicks into place. Once secured, connect the control wiring to the terminals according to your circuit diagram. Verify that all connections are tight and that the contactor operates smoothly before restoring power to the system.

What to consider before purchase

• Verify compatibility with your existing 22.74 contactor model
• Ensure the control voltage requirements match your system design
• Check available space within your electrical panel for the additional width

For optimal performance and safety, always ensure that the auxiliary contact block is installed by a qualified professional. Regularly inspect the terminal connections during routine maintenance to prevent signal loss due to vibration or thermal expansion.
