3WA9111-0AE15 SIEMENS

The 3WA9111-0AE15 is an undervoltage release (UVR-t) accessory designed for use with 3WA and 3WL series circuit breakers from Siemens. This device provides protection against undervoltage conditions, ensuring that the circuit breaker trips when the voltage drops below a certain threshold. It features a time delay function, adjustable from 0.2 to 3.2 seconds, which prevents nuisance tripping due to momentary voltage dips. The undervoltage release is compatible with both AC and DC power sources, specifically designed to operate within a voltage range of 110-127 V AC and 110-125 V DC. This flexibility makes it suitable for a wide range of applications. The UVR-t enhances the safety and reliability of electrical systems by automatically disconnecting the circuit in the event of an undervoltage situation. This helps to prevent damage to connected equipment and ensures the overall stability of the electrical network. Its precise time delay setting allows for customization based on the specific requirements of the application, optimizing performance and minimizing unnecessary interruptions. The 3WA9111-0AE15 is an essential component for comprehensive circuit protection.
