Circuit Protection

The JB is a DC circuit breaker specifically designed for multi-string photovoltaic (PV) installations. It ensures the safety and efficiency of solar energy systems by protecting the cables between photovoltaic modules and the inverter from overloads and short circuits.

Key Features

  • Dedicated Protection: Guards the connections between each string of PV modules and the inverter.
  • Installation Flexibility: Easily integrates into a PV protection enclosure at the end of each string.
  • Polarity Insensitive: Safe operation with (+) and (-) wires, which can be connected inversely without risk.
