trait
High-performance protection: It can quickly respond to faults in the power system, such as short circuit, grounding fault, etc., and accurately remove the fault part to ensure the stable operation of the power system.
Wide operating voltage range: Support 10 ~ 35 V DC, suitable for different power system requirements.
High reliability: The metal housing and IP67 protection class design ensure that the device can still work stably in harsh environments.
Adjustable sensitivity: Adjust the sensitivity through the potentiometer to adapt to different application scenarios.
Bright ring LED: provides clear visual indication.
