NON-POLAR SELENIUM SURGE SUPPRESSOR

40 PLATES, 4″ X 5.3″, P/N 5500C

Surge suppressors are used to protecting 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 a normal “off” state. Surge suppressors can be polar (for direct current circuits) or non-polar (for alternating current circuits) and can be assembled in different configurations to offer surge protection from 3A to 130A.

The following tests were performed:

  • Test 1: 480 VDC was applied at Terminal 1 and RTN on Terminal 2.
  • Test 2: 480 VDC was applied at Terminal 2 and RTN on Terminal 1.
