Product Description

The JB is a DC circuit breaker dedicated to multi string photovoltaic installations.

Storage -40 to 85 degree

- 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.
- To ensure the safety of the installation, it is necessary, depending on the various types of application, to combine the JB with:
a residual current device at the AC end
a fault passage detector (insulation monitoring device) at the DC end
an earth protection circuit breaker at the DC end
- In all cases, fast action on site will be required to clear the fault (protection not ensured in the event of a double fault).
- JB is not polarity sensitive: (+) and (-) wires can inversed without any risk.
- The JB is: delivered with three inter-pole barrier to provide increased isolation distance between two adjacent connectors.
