EMITER DCAC Connection Distribution Board IP65 with DC Surge Protection Dehn 1000V Type 1+2, 2 x PV String, 2 x MPPT // AC Surge Protection Dehn Type 1+2, 20A 3-F

The EMITER EM-214 DCAC hermetic connection box is designed for photovoltaic installations, allowing the distribution and protection of two module strings (2 x module strings on 2 MPPT). The enclosure design provides a degree of protection IP65 and is suitable for surface mounting; the enclosure is equipped with transparent doors and made of halogen-free impact-resistant plastic.

The manufacturer of the device is Emiter Sp. z o.o. (Katowice), a company specializing in solutions for photovoltaic installations and electrical equipment. The offered variant EM-214 DCAC uses top-class third-party components: DC and AC surge protectors from Dehn and a three-phase circuit breaker from Noark.
