Switch disconnector for DC side isolation of PV systems ABB

The S800PV-M provides isolation protection up to 125A and 1200VDC with Icw=1.5kA in accordance with IEC 60947-3.

With highly compact design for installation on the DIN rail, the S800PV-M switch disconnector offers safety relevant isolation properties. As master switch for PV systems, the whole DC side can thus be safely isolated – locally or remote.

Main benefits

  • Reliable isolation of up to 125 A rated current at ambient temperatures of up to 60 °C without any losses
  • Safe switching of ohmic and inductive loads (inductive loads can occur with long line lengths)
  • Extensive range of accessories


Main Features

  • Minimum dimensions with maximum efficiency
  • Safe disconnection of all poles
  • Polarity independent
  • Fast remote controlled operation with S800-RSU remote switching unit
