Frequently Asked Questions

What is the main function of this 800VDC SPD?
It is designed to protect DC-powered equipment, such as solar inverters and battery systems, from voltage spikes and lightning surges by limiting overvoltages to safe levels.
What does the "Type 2" (T2) classification mean?
Type 2 surge protectors are intended for installation at the distribution level. They protect against indirect lightning effects and switching transients within the electrical network.
Can this device handle outdoor environmental conditions?
The device itself has an IP20 rating and is made with UV-resistant material. It is typically mounted within an IP65-rated enclosure if used in outdoor solar combiner boxes or distributions.
How do I monitor the health of the surge protector?
The device features a visual status indicator on the front panel. If the indicator changes color (usually from green to red), it signifies the module has reached its end of life and needs replacement.
What is the advantage of the 2-Pole (2P) design?
The 2P design provides dedicated protection paths for both the positive (L+) and negative (L-) lines relative to the ground (PE), ensuring comprehensive safety for DC circuits.
Is the installation of this SPD difficult?
No, it is designed for standard 35mm DIN rail mounting and uses standard screw terminals, making it compatible with most industrial and commercial distribution boards.
