These Langir DC circuit breakers are perfectly suited for multi string photovoltaic installations. These DC circuit breakers are designed for solar/PV system protection, located between the solar panels and the inverter, helping prevent against overloads and short circuits (see application diagram). Combined with a switch, the 40a DC Circuit Breaker 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 Circuit breaker can detect and protect against any bidirectional current.

<p style="margin-left:0px;">To ensure the safety of the installation, it is necessary, depending on the various types of application, to combine the circuit breaker with:</p><p style="margin-left:0px;">• a residual current device at the AC end,</p><p style="margin-left:0px;">• a fault passage detector (insulation monitoring device) at the DC end</p><p style="margin-left:0px;">• an earth protection circuit breaker at the DC end</p><p style="margin-left:0px;">In all cases, fast action on site will be required to clear the fault (protection not ensured in the event of a double fault). Langir DC Circuit breakers are not polarity sensitive: (+) and (-) wires can inversed without any risk. The circuit breaker is: delivered with three inter-pole barrier to provide increased isolation distance between two adjacent connectors.&nbsp;Set up your solar pv system protection today.</p><p style="margin-left:0px;">&nbsp;</p><p style="margin-left:0px;">Package Content:</p><p style="margin-left:0px;">1 x DC Circuit Breaker</p>
