3WA9111-0AE13 SIEMENS

The 3WA9111-0AE13 is an undervoltage release (UVR-t) accessory designed for use with Siemens 3WA and 3WL air circuit breakers. This device provides protection against undervoltage conditions, ensuring that the circuit breaker trips when the voltage drops below a certain threshold. It features an adjustable time delay function, ranging from 0.2 to 3.2 seconds, allowing users to customize the response time to suit specific application requirements. The UVR-t is designed to operate on a 48 V DC power supply. This undervoltage release prevents equipment damage and ensures safety by disconnecting the circuit in the event of a voltage drop. The adjustable time delay prevents nuisance tripping due to momentary voltage dips. It enhances the reliability and safety of electrical systems by providing a crucial layer of protection against undervoltage conditions. This accessory is essential for applications where maintaining a stable voltage supply is critical for proper operation. Its compatibility with Siemens 3WA and 3WL circuit breakers ensures seamless integration and reliable performance.
