Constructed to ensure robust electrical circuit management and safety, the unit features an IP65-rated enclosure, providing a high level of protection against dust and water ingress, making it suitable for a variety of challenging environments. The switchgear is equipped with a DC surge protection device (SPD) from Dehn, rated at 1000V, type 2, designed to safeguard against transient over-voltage events, thereby extending the lifespan of connected photovoltaic (PV) system components.

The switchgear accommodates three PV strings and is compatible with three maximum power point tracking (MPPT) inputs, enhancing the efficiency of solar energy systems by optimizing the power output from each PV string. Additionally, it includes an AC SPD, also from Dehn, type 2, which provides surge protection on the AC side of the system. This feature is essential for preventing potential damage to electrical equipment caused by power surges.

With a 50A 3-phase capacity, the switchgear can handle significant electrical loads, making it suitable for commercial and industrial applications where multiple PV strings are common. The inclusion of both DC and AC surge protection within a single unit simplifies installation and maintenance while ensuring comprehensive electrical system safety.
