TII 493-01 AC POWER-STRIP TRANSIENT VOLTAGE SURGE SUPPRESSOR



UL LISTED


The TII 493-01 is a six receptacle AC Power Strip with transient voltage surge suppression designed to suppress fast rising, short duration volt-age transients, typically caused by lightning and switching of inductive loads.

The TII 493-01 consists of solid state protection elements , a resettable thermal cutoff switch and RFI filter housed in a sturdy extruded metal enclosure with a front power cord. In addition, a main on/off switch, and a protection available indicator light are also provided.

The power outlets are oriented and sufficiently spaced to allow plugging in of small step down power converters for home appliances.
