FAQs
Q1. What is the difference between a 1000v dc spd t1+t2 and a type 2 only SPD?
The KY-15T/G1000 combines Type 1 lightning current capability with Type 2 low residual voltage protection,
while Type 2 alone cannot handle direct lightning currents.
Q2. Can the 1000v dc spd t1+t2 be used in residential PV combiner boxes?
Yes, it is suitable for residential and commercial PV combiner boxes operating at 1000V DC.
Q3. Does KY-15T/G1000 include remote alarm contacts?
Yes, alarm terminals (NO/NC) are reserved and rated 220V, 0.5A as specified in the datasheet.
Q4. Which standards does the KY-15T/G1000 comply with?
IEC 61643-31, GB/T 18802.31, CE, UKCA, and RoHS certifications are covered.
