Circuit Protection

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.
JB is not polarity sensitive: (+) and (-) wires can inversed without any risk.
