Westinghouse ECT-5 254A586G06 Current Transformer

The Westinghouse ECT-5 254A586G06 Current Transformer is a 50:5 instrument current transformer designed for accurate current sensing, metering, and protective-relay applications within industrial power distribution systems. Designed for panel- or switchgear-mounted installation, it supports use in switchgear assemblies, substations, motor control centers (MCCs), industrial power panels, and utility distribution equipment where current transformation and circuit isolation are required for heavy‑duty electrical systems. Operating at 25–60 Hz, this transformer provides a 50:5 ratio to feed protection relays and metering circuits while isolating the measurement hardware from the high‑power side. The 50:5 ratio is compatible with common metering and relay inputs used in utility distribution and industrial power networks. Maintenance electricians, power system engineers, and industrial integrators rely on the ECT-5 for replacement maintenance, protective-relay upgrades, retrofit projects, and restoration of legacy Westinghouse electrical infrastructure. Part number 254A586G06, from the ECT-5 transformer series, is commonly paired with compatible replacements such as Westinghouse ECT-5 254A586G11, ABB 50:5 Instrument Current Transformer, and GE Industrial Current Transformer.
