⚡ Product Description

The Surge Protective Device (SPD) is a no-fuse, fail-safe surge suppressor. Complying with standard GB/T18802.1 / EN 61643-11, it supports rated voltages of 275V~, 320V~, 385V~, and 420V~. It features a DIN-rail mountable design with a fail-safe self-protected mechanism, visual indicator, and a maximum discharge capacity of 40kA.

Key Product Benefits:
  • Plug-in design allows live replacement and easy maintenance without considering load current.
  • Internal temperature control circuit breaker technology ensures high safety and no freewheeling.
  • Clear status indication: Green for normal operation, Red for fault/replacement.
  • Optional remote monitoring interface (dry contact) for real-time status tracking.

❓ Frequently Asked Questions
What is the purpose of a DC Surge Protection Device (SPD)?
It is designed to protect photovoltaic (PV) power generation systems from overvoltage caused by lightning strikes or other electrical surges by directing excess voltage to the earth within nanoseconds.
How do I interpret the visual indicator windows?
The visual indicator provides status at a glance: Green indicates the device is operating normally, while Red indicates it has reached its end of life or failed and requires immediate replacement.
Can the modules be replaced while the system is live?
Yes, the pluggable design allows for modules to be replaced live, making maintenance simple and reducing system downtime.
What standards do these products comply with?
Our surge protectors comply with international standards including IEC 61643-31 and EN 50539-11+A1, and have passed certifications such as TUV, CE, and ROHS.
What is the typical response time of the SPD?
The device features high-energy MOV chips that provide a rapid response time of less than 25 nanoseconds.
What is the delivery time for orders?
Generally, small quantities are shipped within 3 days. For standard bulk orders, the lead time is approximately 15-20 days.
