3RV1922-1CP0 SIEMENS

The 3RV1922-1CP0 is an undervoltage release from Siemens designed to enhance the safety and reliability of circuit breakers. This device is specifically engineered for use with circuit breakers in sizes S0 through S3, providing a crucial layer of protection against voltage drops. Operating at 230 V AC with a frequency of 50 Hz, or 240 V AC at 60 Hz, it ensures compatibility with standard power systems. The undervoltage release mechanism is designed to automatically trip the circuit breaker when the voltage falls below a predefined threshold, preventing equipment damage and ensuring operational safety. It features a leading auxiliary switch with 2 normally open (NO) contacts, providing additional signaling capabilities for remote monitoring and control. This auxiliary switch allows for indication of the undervoltage release status, enabling proactive maintenance and troubleshooting. The 3RV1922-1CP0 undervoltage release is essential for applications where maintaining a stable voltage supply is critical for the safe and efficient operation of electrical equipment. Its robust design and reliable performance make it a valuable component in industrial and commercial settings, safeguarding against potential hazards caused by voltage fluctuations. By integrating this undervoltage release, users can significantly improve the overall safety and uptime of their electrical systems.
