The HE103C-9LED is a fully encapsulated, solid state arrestor, used for medium duty protection of 120VAC load relays. The HE103C-9LED is a stand alone device suitable for use in either exposed or protected environments. With no follow current, the HE103C-9LED can repeatedly dissipate 10KA (8 x 20us) surges and immediately self-restore, ready to protect against the next surge.

The HE103C-9LED is just as reliable as the standard HE103C series, but with an additional feature: LED status indication. The high intensity green LED on the top of the unit lets the technician know that the unit is operating normally. If the LED is not illuminated, it is an indication the unit should be replaced.
