GACIA PV Combiner Box,PV Combiner Box with DC Breaker

SCBP-6/2 SCBP Series 6 INPUT 2 OUTPUT 1000VDC PV Combiner Box with DC Breaker

Supporting 6-string PV systems, this IP65-rated DC string box delivers reliable surge protection and overload safeguarding on the solar DC side.

It comes equipped with a PB8Z-63 DC breaker, compliant with IEC60947-2 PV & DC standards, providing dependable overload and short-circuit protection, while the non-polarity design simplifies wiring. A Type 2 DC surge arrester (SPD-T2-DC/3P) handles up to 1000V operation and 40kA discharge current, meeting IEC/EN 61643-31 Type 2 standards for high-capacity surge defense. The DC fuse (NRD-30) operates at 1000V, optionally features an LED indicator, and uses a 10×38mm 16A fuse link for fast and safe maintenance.
