The Edco SPA-60B Series is an economical method of protecting circuitry associ-

ated with 120 VAC interconnect signal lines commonly used in traffic control sys-

tems.

In the presence of normal interconnect line voltage and frequency (60 Hz), the

Edco SPA-60B Series possesses the ideal characteristics of high impedance across

the protector and no impedance in series with the line. In the presence of tran-

sients, the protector appears as very low impedance, thereby shunting the surge

to ground.

The product is offered in two variations. The Edco SPA-60BS protects one circuit

and consists of one lead and a stud (also used for mounting). The Edco SPA-60BS-

2 is identical except it protects two circuits and consists of two leads and a stud.

Refer to ordering information.

Installation Stud Mounting Unit: Connect black lead to interconnect signal line near entry point into cabinet. Shorten lead as much as possible. Bolt unit to clean metal surface bonded to power/earth ground, (cabinet in most cases). Lead Suported Unit: Shorten leads. Connect between interconnect signal line and power/earth ground. Ordering Information NOTE: This product is intended for use on 120 VAC interconnect lines. Do NOT use on AC service or power lines. Emerson Network Power.
