Featuring a DC breaker (PB8Z-63) compliant with IEC60947-2 PV & DC standards, it delivers reliable overload and short-circuit protection with a non-polarity design for easier wiring. A Type 2 DC surge arrester (SPD-T2-DC/3P) rated 1000V and 40kA provides high-capacity surge defense in line with IEC/EN 61643-31 Type 2 standards. The DC fuse (NRD-30) supports 1000V operation, includes optional LED indication, and uses a 10×38mm 16A fuse link for convenient replacement and maintenance.
