The Altech SPCT140/100800/5AVA15CL0.5 is an industrial current transformer designed for DIN rail mounting. It features a primary-to-secondary turns ratio of 800:5 and supports frequencies between 50 Hz and 60 Hz. The device has a primary voltage rating of 720 V and a maximum primary current of 800 A. It offers a burden capacity of 15 VA with a measurement accuracy class of 0.5. Physical dimensions are 140 mm in length, 100 mm in width, and 52 mm in height. The unit operates within a temperature range of 0°C to +50°C and utilizes screw-type termination.
Verify the specific part number against official Altech documentation to confirm compatibility with existing panel layouts and wiring configurations. Ensure that the selected current transformer meets the required accuracy class and burden specifications for the intended measurement circuit. Confirm compliance with relevant regional safety standards before deployment.
Select this model based on the required 800 A primary current rating and 15 VA burden capacity. Ensure the application environment falls within the specified 0°C to +50°C operating temperature range. Verify that the DIN rail mounting style aligns with the enclosure design and that the 720 V primary voltage rating exceeds the system's maximum operating voltage.
This component belongs to the Altech SPCT series of industrial current transformers. These devices are engineered for reliable performance in demanding electrical environments. The series provides various ratios and burden options to suit different metering requirements while maintaining consistent physical dimensions for standardized panel integration.
Direct substitutes include other Altech models within the SPCT series that match the 800:5 ratio, 15 VA burden, and Class 0.5 accuracy. Verify that any replacement maintains identical DIN rail mounting dimensions and terminal configuration to ensure seamless integration without modifying the existing panel structure.
