Emiter EM-112_AC AC Combiner Box (40 A, 3-Phase, IP65)

The hermetic Emiter EM-112_AC AC combiner box is designed for surface mounting in three-phase PV installations. The IP65-rated enclosure comes factory-equipped with a Dehn type 2 surge arrester and a 40 A circuit breaker.

The Emiter EM-112_AC combiner box is a ready-to-connect solution designed for photovoltaic installations with or without an isolated lightning protection system. The PHS 12T enclosure offers space for 12 modules, a transparent door, and halogen-free material with IK08 impact resistance. The box features Class II protection, and the built-in MC4 panel receptacles enable efficient circuit installation. AC side protection is provided by a three-pole 40 A Noark circuit breaker and a dedicated Dehn surge arrester.
