Mã sản phẩm: EOCR-SSD 05, EOCRSSD-05S
Features:
■ Using MCU (microprocessor) real-time processing / high precision, intelligent monitoring of three-phase current characteristics through 2CT.
■ Strong anti-electromagnetic harmonic interference capability. (Example: high electromagnetic harmonic devices such as inverters and soft starters).
■ Digital intelligence displays the cause of the trip, making it easy to find the cause of the malfunction.
■ Manual reset (instant) / electrical reset (long distance) mode.
■ Select the load with the DIP switch: single phase (1P) / three phase (3P).
■ "Fail-safe (N type) / "no failure / safety (R type) protection mode is selected by the dip switch.
