UVT) Plastic case circuit breaker undervoltage release (UVT)}Detailed product description：

The function of the QT molded case circuit breaker undervoltage release (UVT) is to detect the voltage at the incoming terminal of the circuit breaker. When the working voltage in the protected circuit drops to 35%~70% of the voltage, it automatically disconnects the circuit breaker and cuts off the load power supply, protecting the load electrical equipment connected to the circuit breaker from low voltage damage.
Complies with the requirements of GB 14048.1 "General Principles for Low Voltage Switchgear and Control Equipment" standard
Complies with the requirements of GB 14048.2 "Low Voltage Switchgear and Control Equipment - Low Voltage Circuit Breakers" standard

functional structure
Divided into two types of structures: assisted suction and self-priming
Self suction undervoltage is controlled by digital circuits, with strong anti-interference ability, and can pass various EMC and EMI tests
Compatible with various types of molded case circuit breakers ranging from 63 to 1600A both domestically and internationally
