Features: The JB is a DC circuit breaker dedicated to multi string photovoltaic installations. This circuit breaker is designed to protect the cables located between each string of photovoltaic modules and the photovoltaic inverter against overloads and short circuits (see application diagram). Combined with a switch , the JB will be installed in a string PV protection enclosure at the end of each string of photovoltaic modules. It can be locked (by a padlocking device) in OFF position as a safety measure for removal of the PV inverter. Since a fault current can flow in the reverse direction to the operating current, the JB can detect and protect against any bidirectional current.
