Frequently Asked Questions
Q1: What is a Type 1+2 DC Surge Protection Device (SPD)?
A: A Type 1+2 DC SPD is a combined protection device designed to safeguard DC systems (especially photovoltaic solar applications) from both direct lightning strikes (Type 1) and indirect lightning transient surges or switching overvoltages (Type 2).
Q2: How do the Green/Red visual indicators work?
A: The indicators display the operational health of the surge protector. Green indicates that the device is fully functional and protecting the circuit. Red indicates the device has degraded or failed due to surge absorption and must be replaced immediately.
Q3: Is the module hot-swappable or pluggable?
A: Yes, it features a pluggable module design. This makes maintenance and cartridge replacement quick and safe, without needing to dismantle the system wiring.
Q4: What mounting style does this SPD support?
A: It is designed for standard 35mm DIN rail mounting, which makes installation standard, fast, and compatible with most common distribution board structures.
Q5: Can I integrate this SPD with remote monitoring systems?
A: Yes. An optional remote signal contact feature is available, allowing status transmissions to remote control panels or monitoring systems for instant fault notifications.
Q6: What standards and certifications does this DC SPD have?
A: The device conforms to IEC 61643-31, EN 61643-31, and GB/T 18802.31 standards. It holds TUV, CE, UKCA, CB, and IEC certifications, ensuring international compliance and safety levels.
