3WA9111-0AE14 SIEMENS

The 3WA9111-0AE14 is an undervoltage release (UVR-t) accessory designed for use with Siemens 3WA and 3WL air circuit breakers. This device provides critical protection against voltage drops, ensuring the circuit breaker trips when the voltage falls below a predefined threshold. Featuring a time delay function, the UVR-t prevents nuisance tripping caused by momentary voltage dips. The adjustable time delay ranges from 0.2 to 3.2 seconds, allowing customization to suit specific application requirements. This undervoltage release is specifically designed to operate with a 60 V DC control voltage. It enhances the safety and reliability of electrical systems by automatically disconnecting the circuit in the event of an undervoltage condition. This accessory helps to prevent damage to connected equipment and ensures personnel safety. The 3WA9111-0AE14 is easy to install and integrate with compatible Siemens circuit breakers, providing a seamless and reliable undervoltage protection solution. Its robust design ensures long-term performance and dependability in demanding industrial environments. By incorporating this UVR-t, users can significantly improve the overall protection and control of their electrical distribution systems.
