DC Circuit Breakerding Clip

Brand:LS SOLAR
Herkunft des Produkts: CHINA
Compliance with standards: multi standard IEC 60947-2, EN60947-2, GB 14048.2

The JB is a DC circuit breaker dedicated to multi string photovoltaic installations.

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

Compliance with standards: multi standard IEC 60947-2, EN60947-2, GB 14048.2

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.

Combined with a switch , the JB 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 JB can detect and protect against any bidirectional current.

Precautions

To ensure the safety of the installation, it is necessary, depending on the various types of application, to combine the JB 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).
