Siemens Industrial Controls 3RV2901-1A Aux Switch
The Siemens 3RV2901-1A is a lateral auxiliary switch engineered for high-reliability signaling within the SIRIUS modular system. Built specifically for Siemens 3RV2 motor starter protectors, this block features a 1 NO + 1 NC (Normally Open/Normally Closed) contact configuration, enabling simultaneous status feedback and control circuit interlocking. Designed for industrial efficiency, the unit utilizes screw terminals for secure conductor termination and supports a wide range of frame sizes from S00 to S3. Its slim 9.5mm profile allows for compact side-mounting without significantly altering the footprint of the motor protection circuit.
Operating with a rated insulation voltage of 690V and a surge resistance of 6kV, the 3RV2901-1A auxiliary contact block ensures electrical isolation and switching accuracy in demanding HVACR and industrial environments. This SIRIUS auxiliary switch is rated for an operational current of 6A at 24V (AC-15) and maintains an IP20 protection class, providing finger-safe contact safety during commissioning and maintenance. Whether you are integrating a Siemens 3RV2 auxiliary contact for remote trip indication or interlocking logic, this component delivers the consistent performance required for professional-grade power distribution and motor control panels.
Key Benefits- Universal Compatibility: Optimized for all Siemens 3RV2 circuit breaker sizes from S00 through S3 for simplified inventory management.
- Instantaneous Switching: Features a 1 NO 1 NC contact arrangement providing immediate feedback for control systems and fault monitoring.
- Rugged Electrical Design: Rated for a maximum switching voltage of 690V AC and suitable for DC-13 applications up to 250V.
- Efficient Installation: Lateral side-mount design with screw-type terminals facilitates rapid integration into existing panel layouts.
- Certified Reliability: Fully compliant with UL 508 and IEC 60947-5-1 standards for global industrial applications.
- Does this switch support 3RV1 motor starters? This specific model is part of the 3RV2 series; check the specific compatibility chart for 3RV1 cross-referencing as 3RV19 and 3RV29 accessories vary.
- Can I mount multiple auxiliary blocks? The 3RV2901-1A is a lateral mount block; usually, only one lateral block is supported per side on the 3RV2 series breakers.
- What wire gauges are compatible with the screw terminals? These terminals are designed for cross-sections between 0.5 to 2.5 mm² (2x 20...14 AWG) for solid or stranded conductors.
