The SL7-63 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 SL7-63 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 SL7-63 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 SL7-63 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).
SL7-63 is not polarity sensitive: (+) and (-) wires can inversed without any risk.
The SL7-63 is: delivered with three inter-pole barrier to provide increased isolation distance between two adjacent
connectors.
