The Ritz OSKF design has an excellent in-service record spanning well over 25 years, largely due to the safety features offered in the standard unit. Special explosion-proof designs are available upon request.

All housings are cast-aluminum and no painting is required over the life of the unit.

All OSKF current transformers are available with either porcelain or polymer insulators.

For special revenue metering applications, Ritz offers the ERCT (Extended Range Current Transformer) option of the OSKF design. The design incorporates a state-of-the-art core/coil design with the proven OSKF insulation structure. The ERCT offers a 0.15% accuracy from 1A to 4000 A primary.
