Product Description

PV 32 amp circuit breaker with TUV SAA CE

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.

Technical data
Position contact indication - suitability for isolation according to IEC/EN 60947-2 standard.
The presence of the green strip guarantees physical opening of the contacts and allows operations to be performed on the downstream circuit in complete safety.
Increased product service life thanks to fast closing independent of the speed of actuation of the toggle.
