Langir DC Circuit Breakers

<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>
