Three Phase Reactor
with Surge Arrestor
600 Volts AC max., 50/60 Hz
Guard-AC™ PLUS combines the benefits of reactor
and MOV (metal-oxide varistor) technology to provide
enhanced surge/spike protection for variable speed
drive/inverter applications.
Use this product on the input side of variable speed
controllers to offer protection from power line spikes,
voltage transients and even to help reduce the effects
of lightning.
Guard-AC™ PLUS is factory assembled and
prewired. Simply connect three incoming and three
outgoing conductors, and make connection to ground.
The reactor portion of this network absorbs current
surges, while the MOV portion clamps voltage spikes
to acceptable levels. They combine to offer the optimum in electronic controller circuit protection. The
reactor even helps to extend MOV life by reducing
the energy content of spikes prior to reaching the
MOV module.
Three phase MOV modules contain high energy rated
MOV’s offering protection from the most common
transient voltage spikes. Module life is extended due
to additional protection offered by reactor.
Typical Applications Include:
• Adjustable Speed Drives
• SCR Controllers
• Rectifier Circuits
•Elevator Drive Systems
• Machine Tool Controls
•Industrial Controls
• Packaging Equipment
•Printing Presses
Connection Diagram:
Guard-AC™ PLUS reactors with surge arrestors
offer enhanced protection of diodes, transistors,
SCR’s, thyristors, etc. from dangerous voltage spikes
and current surges. They can reduce overall system
operating costs by reducing equipment down time
and increasing system reliability and efficiency.
Guard-AC™ PLUS offers the combined benefits of
both reactors and MOV’s including surge absorption,
spike reduction and harmonic attenuation.
