3VW9011-0AE02 SIEMENS

The 3VW9011-0AE02 from Siemens is an undervoltage release (UVR) designed to enhance the safety and reliability of circuit breakers. This accessory is specifically engineered for use with Siemens 3WL10 circuit breakers and 3VA27 molded case circuit breakers. The UVR unit is crucial for preventing unexpected equipment startup after a voltage drop or failure. It operates at a rated voltage of 30 V AC/DC, making it suitable for a variety of applications. Upon detecting an undervoltage condition, the UVR automatically trips the circuit breaker, disconnecting the power supply to protect connected equipment from damage. This feature is particularly important in industrial and commercial settings where voltage fluctuations can be detrimental. The 3VW9011-0AE02 ensures that the circuit breaker remains open until the voltage returns to a safe and stable level, preventing potential hazards and equipment malfunctions. Its compact design allows for easy integration into existing circuit breaker systems, minimizing downtime during installation and maintenance. By providing reliable undervoltage protection, this accessory contributes to a safer and more efficient electrical system.
