ꢀ Industry’s widest range and lowest cost!

ꢀ Tolerances to ±0.5%, TC’s to ±20ppm

RCD’s OA series offers cost-effective performance for a wide range of

current shunt/sense applications. The non-insulated open-air design

features non-inductive performance and excellent stability/overload capacity.

Numerous design modifications and cutom styles are available...

current ratings up to 100A, surface mount designs, military screening/

burn-in, marking, insulation, intermediate values, etc. Custom shunts

have been an RCD specialty over 30 years! Contact factory for assistance.

ꢀ Available on exclusive SWIFT ^TMdelivery program!

ꢀ Option S: Axial lead (unformed element)

ꢀ Option E: Low Thermal EMF
