3RV2922-1CB0 SIEMENS

The 3RV2922-1CB0 is an undervoltage release designed for use with Siemens 3RV2 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 24 V AC with a frequency of 50 Hz or 60 Hz, making it suitable for various industrial applications. The undervoltage release features a leading auxiliary contact with two normally open (2 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 device utilizes screw terminals for easy and secure electrical connections. This undervoltage release enhances the safety and reliability of electrical systems by preventing equipment from operating under insufficient voltage conditions. It is a crucial component for protecting motors and other sensitive loads from damage due to voltage fluctuations. The 3RV2922-1CB0 ensures that the circuit breaker trips reliably in the event of an undervoltage situation, preventing potential hazards and equipment failures. Its robust design and reliable performance make it an ideal choice for demanding industrial environments.
