SDK24-200-01 200A Miniature Split-Core Current Transformer (CT)
SDK24-200-01 200A Miniature Split-Core Current Transformer (CT)
The SDK24-200-01 is a compact, high-performance split-core current transformer designed for non-intrusive AC current measurement in electrical systems. Its innovative split-core architecture allows for rapid installation without disconnecting conductors, making it ideal for energy monitoring, power quality analysis, and equipment protection in commercial, industrial, and utility applications. With a robust design and precision engineering, this CT delivers reliable performance in diverse environments, from smart buildings to renewable energy installations.
Key Features
Split-Core Design
Enables tool-less installation around existing conductors (up to 200A rated current), eliminating downtime during deployment or maintenance.
Spring-loaded hinge mechanism ensures secure closure and consistent magnetic circuit integrity.
Miniature Form Factor
Compact dimensions (e.g., 24mm core diameter, as implied by the model number) facilitate installation in tight spaces, such as crowded distribution panels or meter cabinets.
High Accuracy & Linearity
Meets IEC 61869-2 Class 1.0 accuracy standards (±1% error) across a wide current range (10% to 120% of rated current).
Low phase displacement (<30 minutes) for precise energy billing and harmonic analysis (up to 15th order).
Durable Construction
Black engineering polymer housing (visible in the image) provides UV resistance, mechanical strength, and flame retardancy (UL94 V-0 rated).
Red insulated lead wires (approx. 24 AWG) with polarity markings for easy integration with meters or data loggers.
Safety Compliance
Rated for 600V CAT III environments, with reinforced isolation between primary and secondary circuits.
Complies with RoHS and REACH environmental directives.
