of a MOV need to be deratedat high temperatures as shown in
Figure 1. Because varistors only dissipate a relatively small
amount of average power they are not suitable 0for repetitive

CIII series varistors for Hi-Temperature operating conditions:
• Phenolic Coated CIII Series devices are available with improved maxi-
mum operating maximum temperature 125°C.
• These devices also have improved temperature cycling performance
capability.
• Ratings and Specifications are as per standard CIII Series except Hi-Pot
encapsulation Isolation Voltage Capability = 500V.
• To order: add X1347 to part number (e.g. V230LA40CX1347)
• These devices are not UL, CSA, VDE or CECC certified.
