Description
Selco T2500-05 3-Phase Relay
Over-Current & Short-Circuit Protection Relay — 450VAC 5A
Condition Used / Tested & Fully Operational
This genuine Selco T2500-05 protection relay is in excellent pre-owned condition. The unit has been thoroughly clean-inspected, and bench-tested to confirm precise dial response, operational latching relays, and active LED indicators. Terminal screws are completely clean, rust-free, and fully functional.
Product Overview
The Selco T2500-05 is a highly robust, marine-certified safety relay engineered for continuous surveillance of three-phase electrical grids. It delivers fast-acting protection for main generators, heavy-duty motors, and primary switchgear installations operating on ungrounded or grounded shipboard networks.
This dual-function protection module features an **instantaneous short-circuit trip** mechanism alongside a **definite-time over-current protection delay**. By adjusting the independent dials directly on the front panel, marine engineers can establish precise safety thresholds to safeguard expensive alternator windings and switchboards while preventing nuisance trips during heavy motor-start transients.
