RCD’s OA series offers cost-effective performance for a wide range of
current shunt/sense applications3. 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.
