Distribution Board – NOARK – SHP-232 AC

The SHP-232 AC distribution board is a modular, ready-to-install panel designed to supply photovoltaic inverters on the AC side. The device provides protection against the effects of short circuits and overloads and protects against surges and direct and indirect lightning strikes on the AC side; thanks to the IP65 protection degree, it is suitable for outdoor installations.

Manufacturer: KENO (Poland) — the catalogue card describes the execution of the distribution board produced by the Polish manufacturer KENO; the distribution board uses overload protection/NOARK circuit breaker Noark Ex9BN 3P B16 and a surge protector from Phoenix (VAL-MS-T1/T2 335/12.5/3+1).
