1 / 7PV Combiner Box
PV Combiner Box (White) 1 String Input 1 Output, Dual 40A DC Breakers & Dual 500V/40kA SPDs
The HA-8Way-2DCB-2SPD-White is a 1-string, 1-output PV combiner box in a white, flame-retardant plastic enclosure, engineered with redundant protection. It integrates two 40A DC circuit breakers for overload and short-circuit protection and two 500V DC surge protection devices, each rated at 40kA max discharge current, for enhanced defence against lightning-induced transients. Rated IP65 against dust and water, it is built for outdoor installation on both on-grid and off-grid PV systems where extra redundancy or bipolar protection is required.
