HE100A AC Surge Protector

For more details call:


The HE100A is a fully encapsulated, solid state arrestor, used for medium duty protection of a 120 VAC power line. The HE100A is a stand-alone device suitable for use in either exposed or protected environments. With no follow current, the HE100A can repeatedly dissipate 20KA (8 x 20us) surges and immediately self-restore, ready to protect against the next surge.
