DC circuit supplementary protectors for photovoltaic C60PV-DC PB108403-50 The C60PV-DC is a DC circuit breaker dedicated to multi string photovoltaic. 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 (of the C60NA-DC type, for example), 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: b a residual current device at the AC end, b a fault passage detector (insulation monitoring device) at the DC end b an earth protection circuit breaker at the DC end (see Practical Advice CA908035). 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.
