3RH2911-1NE22 SIEMENS

The 3RH2911-1NE22 auxiliary switch from Siemens is designed for front mounting on 3RH contactors and 3RT contactor relays. This auxiliary switch features a configuration of 2 normally open (NO) and 2 normally closed (NC) contacts, providing versatile switching options for various control circuit applications. The current paths are arranged as follows: one NO contact through terminals .3/.4, another NO contact through terminals .3/.4, one NC contact through terminals .1/.2, and another NC contact through terminals .1/.2. This arrangement allows for flexible integration into control systems requiring both NO and NC signaling. The screw terminal connections ensure secure and reliable wiring. This auxiliary switch enhances the functionality of the main contactor by providing additional contacts for signaling, interlocking, or other control functions. It is suitable for use in a wide range of industrial applications where reliable auxiliary switching is required. Its robust design ensures long-lasting performance in demanding environments. The 3RH2911-1NE22 auxiliary switch is a crucial component for comprehensive motor control and automation systems.
