SCBP-2/1 SCBP Series 2 INPUT 1 OUTPUT 1000VDC PV Combiner Box with DC Breaker

Optimized for dual-string PV systems, this IP65-rated DC string box provides reliable surge protection and overload protection on the solar DC side.

Incorporating a Type 2 DC surge arrester (SPD-T2-DC/3P), it supports up to 1000V operation with a maximum discharge current of 40kA, compliant with IEC/EN 61643-31 Type 2 standards. The DC fuse (NRD-30) operates at 1000V, features optional LED indication, and uses a 10×38mm 16A fuse link for convenient maintenance. A DC breaker (PB8Z-63) compliant with IEC60947-2 PV & DC standards ensures overload and short-circuit protection, with a non-polarity design for easier wiring.
