1. Current Limit Protection: When a short circuit occurs in the line, current limit protection can be achieved within 1S0U5 to avoid accidents; When the current of the protected circuit exceeds the rated current and the set time (0-60s), current limit protection shall be carried out; When the temp exceeds the set value, start the warning. When the temp exceeds the set warning value by 20?, start the over temp current limit protection. 2. Over Under Voltage Protection: When overvoltage is detected and exceeds the set warning value, an alarm is triggered. When the set warning value is exceeded by 13V, an audible and visual alarm is issued. When undervoltage is detected, an alarm is triggered. When the set warning value is exceeded by 10V, the protector sends an audible and visual alarm . 3. Fault Arc Protection: When a fault arc occurs in the circuit for more than 14 half cycles within 1 second, the protector activates the circuit protection, which plays a monitoring, warning, and protection role for fire hazards such as loose connections, poor insulation, poor contact, and aging and damage of electrical wires. 4. Detection and Measuring Function: When the monitored line leakage exceeds the alarm setting value, an audible and visual alarm is issued, and whether to activate current limiting protection can be preset; Real time statistics of equipment installation circuit electricity consumption, and local and remote reset settings. 5. Silencing Function: When the product detects a malfunction, it emits an audible and visual alarm. The sound of the product's alarm can be eliminated through the silent button on the panel, and the alarm light status will remain unchanged after the sound is muted. 6. Testing Function: When the product is in a no alarm state, press and hold this button for 5 seconds to enter the alarm state. Press and hold the reset button for 5 seconds, and the system will reset the product to its normal working state. During the test, See more

Reset Function: If the product detects a fault in the circuit and emits an audible and visual alarm, after troubleshooting the cause of the fault in the circuit, the product can be reset by long pressing the reset button for 5 seconds to eliminate the alarm state. Silencing Function: When the product detects a malfunction, it emits an audible and visual alarm. The sound of the product's alarm can be eliminated through the silent button on the panel, and the alarm light status will remain unchanged after the sound is muted. Fault Arc Protection: When a fault arc occurs in the circuit for more than 14 half cycles within 1 second, the protector activates the circuit protection, which plays a monitoring, warning, and protection role for fire hazards such as loose connections, poor insulation, poor contact, and aging and damage of electrical wires. Remote Control Function: This current limiting protector has a remote opening function, which can control the connected equipment to open through a DC24V fire , achieving the function of fire linkage. Testing Function: When the product is in a no alarm state, press and hold this button for 5 seconds to enter the alarm state. Press and hold the reset button for 5 seconds, and the system will reset the product to its normal working state. During the test, there will be no opening action.
