3RH2911-2NF02 SIEMENS

The 3RH2911-2NF02 is a front-mounted auxiliary switch block designed for use with Siemens 3RH contactors and 3RT spring-type terminal contactors. This auxiliary switch block provides reliable switching of auxiliary circuits in various industrial applications. It features a 2NC (Normally Closed) contact configuration, ensuring that the circuit is closed under normal conditions and opens when the contactor is energized. The current path includes one NC contact designated for 3RH contactors and another NC contact for 3RT spring-type terminal contactors. The spring-type terminals offer quick and easy wiring, reducing installation time and effort. The terminal designations are .1/.2 for both NC contacts, providing clear identification for wiring purposes. This auxiliary switch block enhances the functionality of the main contactor by providing additional switching capabilities for control and signaling circuits. It is suitable for applications requiring reliable and consistent auxiliary switching performance. The compact design allows for easy integration into existing control systems.
