The ABB S800 series is a 2-pole high performance circuit breaker for photovoltaics, with cage terminal. It is a current limiting device with a maximum breaking capacity of 5kA. It can be used for voltages up to 800V DC. It has two different tripping mechanisms, the thermal tripping mechanism for overload protection and the electro mechanic tripping mechanism for short circuit protection.
