Product Description

The DC 1000V 2P Tongou TOSP 20KA-40KA Surge Protector is a Type 2 photovoltaic SPD designed to protect direct current lines up to 1000 V DC against transient overvoltages caused by lightning and switching operations. It incorporates plug-in modules with status indication (green/red) for quick maintenance and offers an optional auxiliary contact for remote fault signaling. Its ultra-fast response and discharge capacity make it a reliable solution for string boxes, combiners, and DC inputs of inverters.

Main Features

U_cpv 1000 V DC; In 20 kA (8/20 μs wave) and Imax 40 kA (8/20 μs).
Typical residual voltage Up ≈ 4.0 kV (at 1000 V DC).
Response time < 25 ns; high efficiency against fast impulses.
Plug-in modules with status window and extraction key for safe replacement.
Mounting on 35 mm DIN rail; tightening torque approx. 2 N·m; recommended stripping 12 mm.
Operating temperature −40…+70 °C; IP20 in suitable enclosure.

Advantages or Benefits

Effective protection of panels, combiners, and inverters, extending system life.
Quick maintenance: replaceable cartridge without disconnecting wiring.
Greater control thanks to the green/red window and optional alarm contact.
Clean and compact installation on DIN rail, ideal for photovoltaic panels.
Compliance with IEC 61643-31 for PV DC applications, ensuring reliability.

Purpose or Applications

Use in photovoltaic strings, combiner boxes, and DC input of on-grid/hybrid inverters up to 1000 V DC. Recommended for residential, commercial, and self-consumption installations with roof or ground-mounted structures.
