DCAC hermetic distribution box IP65 EMITER with DC surge limiter Dehn 1000V type 1+2, 3 x MPPT / AC Dehn type 1+2, 63A 3-phase EM-1291_DCAC

DCAC Distribution Box – Comprehensive Protection for Photovoltaic Systems

This hermetic DC/AC distribution box (IP65) is designed to provide the highest level of safety and reliability in photovoltaic installations. Equipped with surge arresters on both the DC and AC sides, it effectively protects sensitive system components from the effects of sudden voltage increases. This is an ideal solution for both professional installers and end-users who value long-term and trouble-free operation of PV installations.

Protection and Functionality in One

The distribution box combines distribution, protection, and safety functions, simplifying the installation and configuration of the photovoltaic system. The use of Dehn type 1+2 surge arresters on the DC side (up to 1000V) and Noark type 1+2 on the AC side (63A, 3-phase) minimizes the risk of damage caused by lightning strikes or other network disturbances. Additional protection in the form of a Type A residual current device (63A/300mA) provides protection against electric shock. The design allows for operation of three independent photovoltaic strings and three MPPT paths, making it a versatile solution for various installation configurations.

Construction and Application

The distribution box housing with an IP65 protection rating guarantees complete sealing and resistance to external factors – dust, moisture, or rain. Thanks to this, it can be used both indoors and outdoors without fear of corrosion or damage caused by weather conditions. The distribution box is designed to work with photovoltaic modules on the DC side and inverters equipped with MPPT. It will be suitable for three-phase systems, providing optimal protection and efficiency of the entire installation. Remember to match the parameters of the distribution box to the specifications of the inverter and the characteristics of the PV installation.
