2CCF019636R0001 ABB S802PV-SD125 125 A 2-Pole 800 V DC Switch Disconnector

Why Choose the ABB S802PV-SD125 Switch Disconnector?

The ABB S802PV-SD125 is a high-performance 2-pole DC switch disconnector designed for reliable isolation of photovoltaic circuits. As part of the ABB S800PV-SD series, it provides dependable switching and isolation for high-voltage DC installations, particularly photovoltaic power systems.

Designed in accordance with IEC/EN 60947-3, the S802PV-SD125 combines a 125 A rated current with an 800 V DC rated operational voltage. Its 1.5 kA rated short-time withstand current makes it suitable for demanding DC distribution and photovoltaic applications where safe, positive circuit isolation is required.

The two-pole device is designed for mounting on a 35 mm DIN rail and uses ABB's S800 construction with interchangeable cage terminals. A directly contact-dependent visual indicator provides clear indication of the internal contact position, helping operators identify whether the contacts are open or closed.
