G Series Metal Oxide Varistor General Purpose UL1414 and1449 Approved CSA 097864 Actual Approved Size 85 C Maximum Temperature The G series is the standard metal oxide varistor series from UCC/NCC. These MOVs are available in a wide variety of voltages and sizes, which will make them ideal in most applications where a surge protector is needed. The G series is also ideal because of the variety of UL and CSA approvals. The varistors with a 5mm or 7.5mm lead spacing are available with ammo pack taping. Refer to the Mini -Glossary at the end of the metal oxide varistors section for additional technical information and specifications. Summary of Specifications Radial lead terminals.
