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.
