Secsun QCMB2102 DC combiner box, 2 independent strings, 1000 V, with shunt trip
The QCMB2102 is the DC combiner box for 2 independent strings up to 1000 V DC, complete with a shunt trip coil: an external electrical command opens the disconnector and makes the array safe remotely.
It is what you need when the DC side must be openable from an emergency button or from the building fire system, without climbing onto the roof. String fuses, surge arrester and on-load disconnector are already fitted; the enclosure is suitable for outdoor mounting.
