Type 2 Surge Protective Device (SPD), 1P+N configuration, for a 230 V AC nominal network, with a maximum discharge current (Imax) of 20 kA and a width of 2 modules (2M). It protects the installation against transient overvoltages and is designed for DIN-rail mounting. For the Easy9 EZ9L33620 model, the 20 kA value represents the maximum discharge current; the nominal discharge current (In) is 10 kA, and the maximum continuous operating voltage (Uc) is 275 V AC. Compliant with IEC 61643-11, Type 2.
