SW60-DC

The C60PV-DC 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.

Combined with a switch (of the C60NA-DC type), the C60PV-DC 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.

C60PV-DC 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 C60PV-DC 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).

C60PV-DC is not polarity sensitive: (+) and (-) wires can inversed without any risk.

The C60PV-DC is: delivered with three inter-pole barrier to provide increased
isolation distance between two adjacent connectors.
