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.

The TOMZN TOV1‑PV 2P DC Surge Protective Device (SPD) is a low‑voltage arrester designed to protect DC electrical systems, especially in solar photovoltaic (PV) installations and battery‑powered DC circuits, from instantly damaging overvoltage and transient surges. Built to comply with the IEC/EN 61643‑11 surge protection standard, it features high discharge capacity (20 kA ~ 40 kA) and fast response time to divert harmful surges away from sensitive DC equipment before they reach them. The device also includes thermal disconnect protection for added safety and visual status indicators that show when the module needs replacement, and it installs easily on standard DIN rail systems in combiner boxes or distribution panels.
