For more details call:


The HE100 is a fully encapsulated, solid state arrestor, used for medium duty protection of a 120 VAC power line. The HE100 is a stand-alone device suitable for use in either exposed or protected environments. With no follow current, the HE100 can repeatedly dissipate 20KA (8 x 20us) surges and immediately self-restore, ready to protect against the next surge.

When ordering the HE100, please specify which configuration you will need. The HE100 comes with two #10-32 studs on the top of the unit. The HE100S comes with two #10-32 studs the side. Finally, the HE100W is configured with two 18 inch wire leads. No matter which configuration you choose, you will be assured of the best, most reliable surge arrestor available on the market today.
