Parameter Specification / Typical Value Device Type Protective / Measuring Current Transformer (CT) Primary Rated Current (Ipr) Variable. This is a core parameter determined by the application (e.g., 100A, 200A, 400A, 800A, etc.).

Secondary Rated Current (Isr) Standardized: Typically 1 A or 5 A (This is another key ordering specification). Rated Burden 5 kΩ (at the specified secondary current and frequency). This is the impedance of the secondary circuit (including wires and relay/meter impedance) for which the accuracy class is guaranteed. Accuracy Class Typically 5P or 10P for protection, or 0.5, 0.5S, 1 for measurement. This is a critical ordering parameter. Example: "5P10" where '5' is the composite error in %, 'P' is for protection, and '10' is the accuracy limit factor (ALF). Accuracy Limit Factor (ALF) For protection classes (e.g., 10, 15, 20).

Rated Insulation Level / Voltage Medium Voltage Level, e.g., 12 kV, 24 kV, or 36 kV. This is a primary safety specification and must match the system voltage. Short-Time Thermal Current (Ith) Specified in kA for a short duration (e.g., 1s or 3s). Indicates thermal withstand capability during a short-circuit. Dynamic Current (Idyn) Specified in kA peak.
