Type Specification

CONOX = Conradty - Metal - Oxidvaristor

Part Numbering System:

For Example, 10  M  220  V  B

10 = Nominal Diameter in mm, here: 10 mm
M = Disc with radial leads and epoxy resin coating
220 = Proposed Operating Voltage (Urms)
V = Varistor
B = Tolerance of varistor voltage: +/- 10%  (a closer tolerance is possible)

Wire Forms and Delivery

Either the 'Standard' or the 'Inline' form are available.

The Standard delivery form is:

  • Bulk material in paper bags with variable pieces and variable lead length.
  • Tape and Reel: Taped according to IEC-Standard.
