The TXB7LVR self-resetting over- and under-voltage circuit breaker uses a small circuit breaker with short-circuit overload protection as the main switch, and is equipped with an ultra-small intelligent electrical operating device with a relay to detect the power supply voltage and realize over-voltage or under-voltage trip protection and after voltage recovery. The function of the automatic recovery circuit ensures the safe operation of the load equipment within the normal voltage range. Compared with ordinary overvoltage and undervoltage protectors, the self-resetting overvoltage circuit breaker eliminates the trouble of wiring, and the installation is more convenient and quicker without considering the upper and lower wiring problems. The integrated self-reset overvoltage protector has a more concise and comfortable appearance, and is the best choice for high-end residential places. It is mainly suitable for occasions where the grid voltage is unstable or equipment protection that is sensitive to voltage changes.
The self-resetting over- and under-voltage circuit breakers comply with JGJ242-2011 "Code for Design of Residential Buildings" and "Self-resetting Over- and Under-Voltage Protectors (OUPA) Standards". This series of products has a good human-computer interaction interface with small and compact size, high breaking capacity, more reliable action and stable performance.
Self-resetting overvoltage and undervoltage circuit breakers are suitable for places with unstable voltages and are very popular in Africa and Southeast Asia. The main function: 1. Overload protection; 2. Short-circuit protection; 3. Isolated circuit; 4. Leakage protection; 5. Over-voltage protection; 6. Under-voltage protection; 7. Self-recovery function
