The CA Series of transient surge suppressors are industrial high-energy disc varistors (MOVs) intended for special applications requiring unique electrical contact or packaging methods provided by the customer.
  • The electrode finish of these devices is solderable and can also be used with pressure contacts.
  • Discs of the same diameter may be stacked.
  • This series of industrial disc varistors are available in three diameter sizes of 32, 40, and 60mm, with disc thicknesses ranging from 1.8mm minimum to 32mm maximum.
  • They offer a wide voltage range of from 130 to 2800 V M(AC)RMS .
