Why Choose the ABB S802PV-SP8 PV String MCB?
The ABB S802PV-SP8 is a high-performance 2-pole photovoltaic miniature circuit breaker (MCB) designed specifically for overcurrent protection of PV strings and other DC circuits in solar power installations. As part of the ABB S800PV-SP series, it combines reliable circuit protection with a compact modular format suitable for professional photovoltaic distribution systems.
With a rated current of 8 A and a 5 kA short-circuit breaking capacity, the S802PV-SP8 is engineered to disconnect affected circuits when overcurrent or short-circuit conditions occur. Its photovoltaic-specific design makes it suitable for protecting individual strings and associated DC cabling within solar generation systems.
The 2-pole configuration provides simultaneous protection and disconnection of both conductors in compatible PV circuits. ABB's S800 modular platform provides robust construction for demanding electrical installations, while DIN-rail mounting allows straightforward integration into PV combiner boxes, distribution boards and DC protection panels.
