ASCO Model 251 (Edco SHP Series) Surge Protective Device

120 or 240 VAC | 58.5 kA

The ASCO Model 251 (Edco® SHP) Surge Protective Device's hybrid design exhibits performance levels unattainable with simple "shunt type" protectors. The two active clamp stages, large inductor and shunt capacitance effectively halt high rate-of-rise surge waveforms, thus preventing initial voltage overshoot.
