 SPA-60B
Series
120VAC Interconnect Signal
The SPA-60B is an economical method
of protecting circuitry associated with 120VAC interconnect signal
lines commonly used in traffic control systems.
In the presence of normal interconnect line voltage and frequency
(60Hz), the SPA-60B possesses the
ideal characteristics of high impedance across the protector and
no impedance in series with the line. In the presence of transients,
the protector appears as very low impedance, thereby shunting the
surge to ground.
The product is offered in four variations. The SPA-60BL
protects one circuit and is furnished with two leads. The SPA-60BL-2
is identical except it protects two circuits and is furnished with
three leads.
The SPA-60BS protects one circuit
and consists of one lead and a stud (also used for mounting). The
SPA-60BS-2 is identical except it
protects two circuits and consists of two leads and a stud. Refer
to ORDERING INFORMATION below.
