Single contact block for 22mm head, 1 NC, screw terminals ZENL1121

Single contact block from the Harmony XALD series is an element dedicated to building reliable and flexible control circuits. Designed to work with 22 mm diameter heads, it enables quick configuration and replacement of buttons and selector switches. Thanks to the use of screw terminals, it ensures a secure and durable connection with wires.

This contact block is compatible with Harmony XB5 components and XAPS control stations, allowing for the creation of complex control systems. Its design allows for easy installation and replacement, minimizing downtime in the event of a failure or the need for modification. Using this contact block translates to increased work efficiency and installation safety.

Construction features and application

The contact block has one normally closed (NC) contact, which means that the circuit is closed at rest and opens when the button is pressed or the switch is flipped. The rated operating current for AC-15 at 230 V is 3 A, making it suitable for controlling various electrical devices. Mounting is directly to the base, ensuring stability and a secure connection.

This block finds application in a wide range of industrial applications, such as:

• Control panel construction
• Machine and device control
• Signaling and alarm systems
• Building automation
