Description
Product Overview
The Hager HR510 is an industrial-grade, 4-pole electronic residual current protection relay designed for commercial switchboards, automated control panels, and heavy-duty distribution systems. This precision Type A safety relay works in tandem with an external core-balance toroidal transformer to continuously monitor electrical networks for insulation faults and hazardous earth leakage.
Featuring front-accessible analog dials under a clear protective flip cover, it allows electrical contractors and maintenance technicians to customize both current sensitivity thresholds and trip time delays to match precise local system requirements.
