DC circuit breaker's Application

SL7-63 Series DC1200V 63A DC Circuit breaker, apply to rating current 63A or less, It is mainly used for the overloading and short circuit protection in DC distribution system equipment and electric equipment. It can be widely used in electric, post, traffic, mining enterprise and different kinds of fields. In present China, our products in the case grade rating voltage is highest compared to the same products.

Standard

Products according IEC60947, GB14048.2, IEC60898.2 AS/NZS60898.1, AS/NZS60898.2, AS/NZ61009
Standard.


Overload Characteristic



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.

SL7-63 DC MCB Main characteristics
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.
Pre-wired product: Input / Output on the same side.
