3RV1902-1AP0 SIEMENS

The 3RV1902-1AP0 is an undervoltage release designed for Siemens circuit breakers, specifically sizes S00 through S3. This device provides crucial protection by automatically tripping the circuit breaker when the supply voltage drops below a safe threshold. It operates on a 230 V AC power supply at 50 Hz or a 240 V AC power supply at 60 Hz, making it suitable for various electrical systems. Upon detecting an undervoltage condition, the release mechanism swiftly disconnects the circuit, preventing damage to connected equipment and ensuring personnel safety. The undervoltage release enhances the overall reliability and safety of electrical installations by providing an automatic response to voltage fluctuations. Its compact design allows for easy integration into existing circuit breaker setups without requiring significant modifications. This device is essential for applications where maintaining a stable voltage supply is critical for uninterrupted operation and equipment protection. By incorporating the 3RV1902-1AP0, users can mitigate the risks associated with voltage drops and ensure the safe and efficient operation of their electrical systems. Furthermore, it helps in preventing unexpected restarts of machinery after a voltage recovery, which could potentially lead to hazardous situations. This undervoltage release is a vital component for safeguarding electrical circuits and connected equipment.
