AC connection distribution box hermetic IP65 EMITER with AC surge limiter Dehn type 1+2, 40A 3-phase EM-50_AC

AC connection box – comprehensive protection for photovoltaic installations

The EMITER brand AC connection box with IP65 protection is a ready-made solution for the safe connection of a photovoltaic installation. Equipped with a Dehn type 1+2 surge arrester with a current of 40A and a type A 63A/300mA residual current device (RCD), it provides effective protection against the effects of atmospheric overvoltages and damage caused by short circuits. The construction in an IP65 protection class housing guarantees reliable operation even in harsh weather conditions.

Safety and functionality in one device

The key element of this connection box is the Dehn type 1+2 surge arrester, which protects sensitive components of the photovoltaic installation, such as the inverter, against sudden voltage increases. The type A residual current device with a sensitivity of 300mA additionally protects users from electric shock and also detects and isolates ground faults. Combining these two functions in one device guarantees comprehensive protection and peace of mind.

Construction and application

The connection box is designed for wall mounting, both indoors and outdoors. The hermetic IP65 housing protects the components from moisture, dust and other external factors. It is ideal for use in photovoltaic installations with a power of up to 40A (three-phase), where high reliability and safety are required. The connection box should be mounted near the inverter on the AC side of the installation. Thanks to its compact size and ease of installation, it is a convenient solution for both professional installers and end users.
