Q1
Is this product compatible with my system?
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. If unsure, provide your specifications, and we’ll recommend the right product.
Q2
How do I select the correct current rating?
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?
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
What is the maximum PV voltage capacity of this Surge Protective Device?
This Surge Protective Device is specifically engineered to handle a maximum PV voltage of up to 1200V DC, making it highly suitable for modern high-voltage solar photovoltaic installations.
Q5
What are the Nominal and Maximum Discharge Currents?
The device has a Nominal Discharge Current (In) of 20kA and a Maximum Discharge Current (Imax) of 40kA, providing robust protection against lightning strikes and system surges.
Q6
How is this protection device mounted and what is its protection degree?
The unit is designed for quick and secure mounting on standard 35mm DIN Rails. It features an IP20 protection degree, providing safe enclosure housing for standard electrical panels.
