Emiter EM-353 AC Hermetic Distribution Board (20 A, 3-phase)

The Emiter EM-353 AC hermetic distribution board is designed for surface mounting in three-phase photovoltaic systems. The product features an integrated Dehn type 1+2 surge protective device (SPD) and a 3-pole 20A miniature circuit breaker (MCB) with B tripping characteristics.

The Emiter EM-353 AC IP65 junction box is designed for photovoltaic systems with or without an isolated lightning protection system. The PHS 8T enclosure accommodates 8 modules and features a transparent door for easy visual inspection. The halogen-free plastic used offers an IK08 impact resistance rating and has successfully passed the glow-wire test at 650 °C.
