The ESCTC Series Solid Core Current Transformer provides a reliable way to monitor current circuits by converting large primary currents into a 5 A secondary signal suitable for meters and protective relays. This model, ESCTC325 2005A, covers a primary current range of 250630 A and features a 200:5 A ratio. Key benefits Safe isolation: Provides isolation between voltage power conductors and measurement/control circuits. Standard 5 A output: The secondary current is 5 A, compatible with common meters, relays, and data acquisition systems. Wide primary range: Accepts 250630 A on the primary, allowing monitoring across varying load conditions without swapping devices. Solid core design: Built for durability and stable performance in environments with electrical noise and temperature variation. Easy installation: Designed to be installed around a single primary conductor within equipment or switchgear, simplifying retrofits and maintenance. Consistent performance: Maintains a reliable current transformation ratio (200:5 A) for accurate metering and protection inputs.
