The EM-528N_DCAC switchgear is designed to offer a robust solution for solar photovoltaic (PV) systems requiring efficient and safe electrical distribution and protection. Encased in an IP65-rated enclosure, this switchgear provides a high level of protection against dust and water ingress, making it suitable for a variety of installation environments.

Equipped with a Surge Protection Device (SPD) rated at 1000V for DC applications, the unit ensures Type 2 protection against transient over-voltage, which is essential for safeguarding sensitive electronic components in PV systems. It supports two PV strings and is compatible with systems that have two Maximum Power Point Tracking (MPPT) inputs, enhancing the overall energy efficiency of the solar array.

Additionally, the switchgear includes an AC SPD, also of Type 2, which is designed to protect against surges in the AC circuit. The AC side features a 16A 3-phase circuit breaker and a Residual Current Device (RCD) rated at 40A with a 300mA trip sensitivity, providing further safety measures by detecting and preventing electrical leakages that could lead to shock hazards or fire risks.

This switchgear is engineered to facilitate the safe operation and longevity of solar PV installations, ensuring electrical components are shielded from potential over-voltage damage while maintaining continuous system performance.
