2-Pole DC Surge Protection – Designed to protect DC power systems (e.g., solar PV strings and DC distribution) from damaging voltage surges and transient spikes.
High Discharge Capacity (20 kA ~ 40 kA) – Can absorb and divert large surge currents caused by lightning or fast transient overvoltage events, helping safeguard connected equipment.
Rated for Up to 1000 V DC – Suitable for high-voltage DC systems typically used in photovoltaic (solar) installations and other DC circuitry.
Fast Response Time – Activates quickly (in microseconds) to reduce exposure to harmful transient events in the DC network.
Low Residual Voltage – Limits the voltage that passes through to sensitive devices during a surge, minimizing potential damage
Thermal Disconnect Safety – Built-in thermal disconnect devices improve reliability by isolating the unit if internal components overheat.
Visual Status Indicators – Color-coded indicators (e.g., green for normal, red for fault) provide quick feedback on protection status.
DIN-Rail Mountable – Easy installation in DC combiner boxes, PV distribution panels, and electrical cabinets using standard DIN-rail mounting.
