ABB High Performance S800 MCB, 4P, 125A, 1200V DC, 1.5 kA Breaking Capacity

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. Here again, consideration was given to the special ambient influences of photovoltaic systems up to 1200 Vdc even at the development stage:

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
