2‑Module 600 V DC Type 2 PV Surge Protector – SPD PV600
Shield your solar inverter and DC cabling with the SPD PV600 — a compact, all‑purpose Type 2 surge protection device tailored for photovoltaic systems operating at up to 600 V DC. Engineered for reliability and ease of maintenance, this DIN‑rail mounted unit delivers fast, modular protection before your inverter.
Key benefits at a glance
-
Specifically for PV systems – protects the DC side ahead of the inverter at a maximum continuous voltage of 600 V DC, suitable for lower-voltage solar arrays, string boxes, and combiner units.
-
Compact 2‑module form factor – DIN‑rail mounted with pluggable, replaceable modules, making servicing quick and cost‑effective .
-
Clear visual status & optional remote signalling – onboard LED indication (green = OK, red = fault) with optional remote contact signal ensures system health monitoring.
-
Robust surge-handling – rated for 20 kA nominal discharge current, up to 40 kA maximum (8/20 µs), with fast response time under 25 ns for high-energy transient suppression .
-
Certified & durable – compliant with IEC 61643‑1 and EN 61643‑11, features UKCA & CE marking, flame-retardant housing rated UL94 V‑0, and protection class IP20.
