Product Description

The DC 1000V 3P Tongou TOSP 20KA-40KA Surge Protector protects photovoltaic systems up to 1000 V DC with topologies requiring three poles (for example, strings with specific configuration or multi-input combiner boxes). Its Type 2 architecture, plug-in modules, and visual signaling simplify maintenance, while its high discharge capacity safeguards panels, wiring, and inverters against surges from lightning and switching operations.

Main Features

U_cpv 1000 V DC; In 20 kA (8/20) and Imax 40 kA (8/20).
Typical residual voltage Up ≈ 4.0 kV at 1000 V DC; I_imp ≈ 6.5 kA (10/350).
Response time < 25 ns; high protection against fast transients.
Plug-in modules with green/red window and front extraction for replacement.
DIN 35 mm mounting; tightening torque approx. 2 N·m; stripping 12 mm; terminals up to 25–35 mm².
Environmental range −40…+70 °C; IP20 in suitable enclosure.

Advantages or Benefits

Balanced protection of strings and inverter input, reducing failures and downtime.
Lower operating cost thanks to replaceable cartridges and visual diagnostics.
Possibility of signaling to PLC/SCADA via optional auxiliary contact.
Compact and tidy installation in photovoltaic panels.
Compliance with IEC 61643-31 for demanding PV DC environments.

Purpose or Applications

Recommended for use in combiner boxes, string panels, and near inverters in 1000 V DC systems for residential, commercial, and industrial applications. Suitable for rooftop, ground-mounted, and solar carport structures.
