Frequently Asked Questions
Q1: Is this product compatible with my system?
A: This product is designed for DC circuits (e.g., solar PV systems), supporting voltages from 250V to 1000V DC and current ratings from 1A to 63A. Please match the model to your system’s voltage and current requirements.
Q2: How do I select the correct current rating?
A: Choose a current rating slightly higher than your actual operating current (e.g., for an 18A load, select a 20A model). This prevents overloads while avoiding nuisance tripping from startup surges.
Q3: What does "Type C trip curve" mean?
A: Type C curve is suitable for moderate inrush current applications (e.g., PV inverters, motors). It trips instantly at 5-10x the rated current, tolerating short startup surges without false triggering.
Q4: How long is the mechanical and electrical lifespan?
A: This device is built for durability, featuring a mechanical life of 10,000 cycles and an electrical life of 4,000 cycles under standard operating conditions.
Q5: What is the rated residual operating current?
A: The rated residual operating current for this unit is 100mA, which is calibrated to provide effective leakage protection for your electrical circuits.
Q6: Can this be used for both 50Hz and 60Hz grids?
A: Yes, the product is rated for a frequency of 50/60Hz, making it universally compatible with standard AC power grids.
