Product Overview

Symap‑F is dedicated feeder digital protection relay for industrial power‑distribution systems. It monitors current, voltage and frequency of outgoing feeder circuits, trips circuit‑breaker upon short‑circuit, overload and earth‑fault faults to isolate fault section. Widely used in plant‑power distribution cabinets and substation control panels. Surplus and refurbished tested spare feeder protection relay.

Application Notes

‑ Set current‑transformer ratio and protection time‑delay parameters according to power‑system design. ‑ Typical deployment: Distribution‑network feeder protection relay spare‑part stocking.
