SUNPOLE SL7P-63 Series Non-Polarity DC Circuit Breaker is designed for Solar PV application. The working voltage is from DC 12V to DC 1000V and the rated current is from 6A to 63A. Breaking capacity up to 6kA.
Due to the no polarity performance, the SL7P Series DC MCB can be used between solar inverter and batteries. It can protect the battery charge current and discharge current.
The rated voltage of 1P Solar DC Circuit Breaker is DC 250V which can be used between 12V to 250V.
For solar photovoltaic system, it’s important to protect the solar panels, barrary system and solar inverters from overload and short circuit.
Application:
Widely used in DC panel, DC distribution cabinet, DC combiner box, energy storage, photovoltaic, wind power station distribution box system, communication distribution box protection system, and can also be used for infrequent on-off conversion of lines under normal conditions.
YRO DC Switch designed the arc extinguishing chamber adopts a multi-grid
arc extinguishingchamber, and each pole is equipped
with 2 arc extinguishing chambers to enhance the
arc extinguishing capacity. The static contact arc ignition design is more conducive to the
arc entering the arc extinguishing chamber. Flame retardant rating of UL94 V-0.
