Description
Overview
The Siemens 3RH2921-2DA11 is an auxiliary switch block from the SIRIUS innovation range, designed for lateral mounting on the side of contactors. This compact unit expands the control capabilities of your motor starter setup by providing additional signaling and interlocking contacts. With its spring-loaded terminal system, it is ideal for environments prone to high vibration, ensuring constant contact pressure without the need for periodic re-tightening.
Key Features & Function
-
Lateral auxiliary switch with 1 NO + 1 NC contacts
-
Left contacts: 51/52, 63/64
-
Right contacts: 31/32, 43/44
-
Current path configuration: 1 NC, 1 NO
-
Spring-loaded terminal design for fast, secure wiring
-
Ideal for 3RT2 contactors and 3RH2 contactor relays
-
Robust design for reliable industrial automation performance
Benefit
-
Space-Efficient Design: Lateral mounting allows for expansion without increasing the depth of the control cabinet.
-
Vibration Resistance: Spring-loaded terminals provide a "gas-tight" connection that is superior to screw terminals in high-movement applications.
-
Versatile Compatibility: Seamlessly integrates with the entire Siemens 3RT2 and 3RH2 product families.
-
High Reliability: Built to industrial standards for long mechanical and electrical service life.
