3RV2922-2CV0 SIEMENS

The 3RV2922-2CV0 is an undervoltage release designed for use with Siemens 3RV2 series circuit breakers. This device provides protection against voltage drops, ensuring that the circuit breaker trips when the voltage falls below a certain threshold. It operates at 400 V AC and 50 Hz, making it suitable for standard European power systems. The undervoltage release features a leading auxiliary contact with 2 normally open (NO) contacts, providing additional signaling capabilities. These auxiliary contacts can be used to indicate the status of the undervoltage release or to trigger other control circuits. The 3RV2922-2CV0 utilizes spring-type terminals for easy and reliable connection. Spring-type terminals offer a secure and vibration-resistant connection, reducing the risk of loose connections and improving overall system reliability. This undervoltage release is essential for applications where maintaining a stable voltage supply is critical for safe and reliable operation. It helps to prevent equipment damage and ensures that the circuit breaker trips in the event of a voltage drop, protecting the connected load. By incorporating this undervoltage release, users can enhance the safety and reliability of their electrical systems.
