DCAC hermetic distribution box IP65 EMITER with surge protection device DC Noark 1000V type 2, 1 x MPPT / AC heating Noark type 2, 10A 3-phase EM-75N_DCAC

Safety and photovoltaic installation protection

The DC/AC EMITER distribution box with surge limiter is a key element of every modern photovoltaic installation. It provides comprehensive protection against the effects of overvoltages, both on the direct current (DC) and alternating current (AC) side, which translates into a longer lifespan and reliability of the entire system. A hermetic housing with an IP65 protection rating guarantees safe use in harsh weather conditions, both outdoors and in rooms with high humidity.

Design and application

The distribution box is designed for mounting near photovoltaic panels or an inverter. It allows for safe connection of PV strings to the inverter, and also provides protection against damage caused by sudden voltage surges. Equipped with a Noark type 2 DC surge limiter (up to 1000V) protects the photovoltaic string, while a Noark type 2 AC surge limiter (10A) protects the alternating current side. Additionally, a built-in residual current device (RCD) with a sensitivity of 100mA increases safety by detecting and interrupting leakage currents.

Advantages for the installer and end user

• Comprehensive protection: Integrated DC and AC protection minimizes the risk of damage to the installation caused by overvoltages.
• Hermetic IP65 housing: Guarantees resistance to weather conditions and the possibility of outdoor mounting.
• Easy installation: A well-organized interior facilitates connection of wires and servicing of the distribution box.
• Safety of use: The built-in RCD provides additional protection against electric shock.
• Compliance with standards: The distribution box meets the requirements for the safety of photovoltaic installations.
• MPPT operation optimization: Support for one PV string and one MPPT regulator allows for efficient management of solar energy.

Thanks to this solution, the installer can be sure that the photovoltaic system is properly protected, and the end user – that their investment is durable and safe. This distribution box is not only a technical element, but above all an investment in peace of mind and long-term benefits of owning a photovoltaic installation.
