DC/AC hermetic switchboard EMITER with DC surge arrester Dehn 1000V type 1+2, 2 x PV string, 2 x MPPT, AC surge arrester type 1+2, 16A 3-phase EM-92_DCAC

DC/AC Hermetic Distribution Box – Comprehensive Protection for Photovoltaic Installations

This hermetic EMITER distribution box, equipped with Dehn surge arrestors, is a ready-made solution for photovoltaic installations, ensuring the safety and reliability of the system. Designed to protect against the effects of surges on both the DC (direct current) and AC (alternating current) sides, it is a key element of any modern PV installation.

The distribution box is adapted to work with two strings of photovoltaic modules, supporting two independent MPPTs (Maximum Power Point Trackers). This ensures optimal use of solar energy, even in variable lighting conditions. Additionally, the built-in AC surge arrester (16A, 3-phase) protects against damage on the grid side. The whole is enclosed in a housing with a high degree of protection IP65, guaranteeing resistance to weather conditions and dust.

Functionality and safety in one

The design of the distribution box has been carefully thought out in terms of ease of installation and connection. MC4 connectors facilitate quick and easy connection to photovoltaic modules. Inside there are two DC surge arrestors Dehn type 1+2, which effectively suppress voltage surges generated by lightning strikes or network disturbances. The AC type 1+2 surge arrester protects against overvoltages on the AC side. Additionally, a 3-phase overcurrent switch with a rated current of 16A provides an additional layer of protection against overloads and short circuits.

• Protection against DC and AC surges: Integrated Dehn surge arrestors provide comprehensive protection of the photovoltaic installation against the effects of lightning strikes and network disturbances.
• Ready to connect: MC4 connectors minimize installation time and facilitate connection to photovoltaic modules.
• High resistance to weather conditions: The housing with IP65 protection guarantees tightness and durability even in harsh outdoor conditions.
• MPPT work optimization: Support for two PV strings with two MPPTs allows for maximum use of solar energy.
• Circuit safety: 3-phase 16A overcurrent switch protects against overloads and short circuits, ensuring safe system operation.

Specification for professionals
