SELENIUM SURGE SUPPRESSORS, P/N E25HX9EN1

Surge suppressors are used to protect circuits from transients (sudden, brief increases in voltage). Transients of widely varying magnitudes are caused by such circuit components as motors, coils, magnets, relays, and transformers. They are found in all electrical systems and they are notorious for damaging diodes, SCRs, transformers, triacs, and relay contacts.

Surge suppressors can be connected across individual components, part of a circuit, or to supply to an entire circuit. When the voltage is normal, they are in an “off” state and do nothing. However, when a transient raises the voltage they react very quickly and conduct the excess around the components they protect. When the transient has passed they return to normal “off” state. It is cheaper to use surge suppressors than it is to buy new components or have equipment out of service. Surge suppressors can be polar (for direct current circuits) or nonpolar (for alternating current circuits) and can be assembled in different configurations to offer surge protection form 3A to 130A.
