ОПИСАНИЕ ПРОДУКТА
ASEA BROWN BOVERI 1SDA073762R1 - UnderVoltage Release (UVR)
This component is an UnderVoltage Release module engineered for seamless integration with ASEA BROWN BOWVERI SACE Tmax XT4 series molded case circuit breakers. It provides essential protection by automatically tripping the circuit breaker when the control voltage supplied to the release coil drops below a predefined threshold, thereby safeguarding connected equipment and processes from undervoltage conditions. This electromechanical accessory is critical for industrial power distribution, motor control centers, and safety-critical applications demanding automatic disconnection upon voltage sag or complete power loss.
