Self-resetting contact block 1NC+2NO screw terminals XENG1491

Self-return contact block – a reliable control element

The XENG1491 self-return contact block is a dedicated component for the XACA control cassette, providing additional functionality in control systems. Mounted on the front of the cassette, it offers a configuration of 1 normally closed (NC) contact and 2 normally open (NO) contacts, allowing for flexible adaptation to application needs.

Design and application

The contact block is designed for front mounting and is characterized by screw connections, which ensure a secure and durable electrical connection. Its design is based on the self-return principle, which means that after releasing the button or lever, the contact returns to its initial position. This solution works particularly well in applications requiring frequent and reliable switching of circuits.

The contact blocks from the Harmony XAC-A series are compatible with various types of enclosures and buttons, allowing the creation of complex control systems. They are used in the industrial sector (e.g., lifts, cranes) and in the service sector, where high reliability and safety are required. Thanks to the possibility of configuration with various elements from the Harmony family, they can be adapted to the specific requirements of a given workstation.
