The ABB S800PV-SP high-performance string protection MCB provides string protection up to 125 A and 1500 VDC with Icu=5 kA in accordance with IEC 60947-2 and Annex P.
The MCB S800PV-SP is specially developed for use in photovoltaic systems. It is designed to provide reliable protection for PV modules and lines against reverse currents from defective strings and AC regenerative feedback due to defective inverters. The high demands of PV systems have been taken into consideration in the development of the S800PV-SP.
Main benefits include selective string shutdown even under load; remote shutdown using working current and low-voltage trips possible; high ambient temperatures; and an extensive range of accessories.
Main features include safe disconnection of all poles; polarity independent; and fast remote-controlled operation with S800-RSU remote switching unit.
