The Westinghouse 1875267A CO-8 electromechanical overcurrent protection relay provides inverse-time protection for electrical power distribution systems, triggering a circuit-breaker trip when current exceeds preset pickup settings. CT-operated with an induction-disc design, it offers adjustable inverse-time characteristics for selective coordination and supports CT input ranges of 0.2–2 A or 4–12 A. This panel-mounted relay protects feeders, transformers, motors, generators, and distribution circuits in utility substations, switchgear, and industrial power systems.
