[COMPREHENSIVE PHASE PROTECTION] This 3 phase sequence relay protector offers dynamic and static phase loss protection for any phase when the device is running or idle. The red indicator light activates with priority to alert you instantly, ensuring your equipment stays safe from unexpected power interruptions and potential damage during both operation and standby modes.
[ WRONG PHASE SEQUENCE DETECTION] Prevent dangerous misconnections with our advanced wrong phase protection feature. If L1 L2 L3 three phase AC power supply is connected incorrectly the yellow indicator light immediately signals the issue allowing for corrective action by simply exchanging any two phases. This ensures your system operates correctly without delays.
[RELIABLE VOLTAGE UNBALANCE PROTECTION] your devices from voltage imbalances that compromise safe operation. When the imbalance rate exceeds 8 percent the red phase loss light illuminates with priority triggering protection. This feature actively monitors power quality and responds swiftly to prevent equipment malfunction or failure caused by uneven voltage distribution.
[DELAY AND LOAD INDEPENDENT OPERATION] When a fault is detected the monitor implements a 1 to 2 second delay before the relay releases providing response time. The protection function remains unaffected by line or load current inrush current unbalanced current or load nature. It delivers consistent full performance across all climates with minimal power consumption under 2W ensuring long term reliable operation without interference from external electrical conditions.
[EASY INSTALLATION WITH DIRECT WIRING] Designed for straightforward setup this protector requires no special motor wiring when used for motor protection. Connect wires directly to the terminal block with NO and COM as normally open contacts and NC and COM as normally closed contacts. The green light indicates correct L1 L2 L3 wiring with relay closed while the device meets GB/T 14048.1
