The SIEMENS 3SU1550-1AA10-1BA0 is a universal 3-fold holder combining plastic and metal components for secure mounting of a single normally open contact with screw terminal connection. Designed for control panels and industrial enclosures, it keeps the contact firmly positioned while allowing straightforward wiring via the screw terminal. The mixed-material construction provides a balance of insulating support and mechanical strength, and the three-fold design streamlines installation where multiple holders are used side-by-side. Use it to simplify assembly and maintain tidy, reliable connections in electrical control systems.
