Riken / Suntree 2‑Pole 1000 V DC Surge Protection Device (40 kA, DIN Rail)

Rated for 1000V DC Applications
Designed for use in high-voltage PV systems, including rooftop and ground-mounted solar arrays.

40kA Maximum Discharge Current (Imax)
Capable of absorbing high-energy transients with peak current up to 40,000 amps (per IEC 61643-31).

2-Pole DC Protection
Provides simultaneous protection for both DC+ and DC− lines, with optional protection to earth (depending on installation configuration).

DIN Rail Mountable
Clips onto standard 35 mm DIN rails for fast and safe installation in combiner boxes, inverter panels, or sub-distribution boards.

Visual Fault Indicator
Integrated status window (typically green/red) provides quick visual confirmation of operational status. Red indicates failure or replacement needed.

Remote Alarm Contact (Optional)
Some models support auxiliary signaling for remote monitoring via SCADA or PLC.

Robust Housing
Flame-retardant thermoplastic enclosure (usually UL94 V-0 rated) offers IP20 protection for internal installations.
