Product Overview

12HEA61A224X2 is heavy‑duty electromechanical auxiliary relay manufactured for power‑generation protection‑and‑control panels. Multi‑pole contact groups are used for turbine trip‑interlock, protection‑relay auxiliary‑signal routing and alarm‑circuit switching. High‑mechanical‑reliability design adapts to plant harsh electromagnetic‑interference environment. Widely deployed inside utility power‑plant control‑and‑protection cabinets. Spare relay unit available as surplus and tested refurbished component for panel‑maintenance and retrofit‑work.

Application Notes

‑ Confirm coil voltage matches control‑circuit supply before installation. ‑ Respect contact‑current rating; do not over‑load switching contacts. ‑ Perform contact continuity test after long‑term storage. ‑ Typical deployment: power‑plant interlock‑auxiliary‑relay spare‑part stocking.
