3RV1982-1AF0 SIEMENS

The 3RV1982-1AF0 is an undervoltage release designed for use with Siemens 3RV1 motor starters in sizes 6, 7, and 8. This device provides critical protection by automatically tripping the motor starter when the supply voltage drops below a safe threshold. It operates within a voltage range of 220 to 240 V AC and 220 to 250 V DC, offering versatility in different power systems. The undervoltage release ensures that the motor is not subjected to potentially damaging low-voltage conditions, preventing equipment failure and extending the lifespan of the motor. It is essential for applications where maintaining a stable voltage supply is crucial for reliable motor operation. Upon voltage recovery, the motor will not restart automatically, preventing unexpected operation and enhancing safety. This feature requires manual resetting of the motor starter, ensuring a controlled and safe restart process. The 3RV1982-1AF0 undervoltage release is a vital component for comprehensive motor protection, safeguarding against voltage fluctuations and ensuring operational integrity. Its robust design and precise voltage sensing capabilities make it a reliable choice for industrial applications. This device contributes significantly to minimizing downtime and preventing costly motor repairs.
