Overview
The Altech SPCT140/1004000/5AVA15CL0.5 is an industrial current transformer designed for DIN rail mounting. It features a primary-to-secondary turns ratio of 4000:5, supporting a primary current rating of 4000 A and a secondary output of 5 A. The device operates within a frequency range of 50 Hz to 60 Hz and has a maximum burden capacity of 15 VA. Accuracy class is specified as 0.5. The unit utilizes screw termination for secure electrical connections and is rated for a primary voltage of 720 V. Physical dimensions include a length of 101 mm, width of 52 mm, and height of 120.4 mm.
Feature Summary
- Provides precise current measurement with 0.5 accuracy class for industrial monitoring applications
- Supports high-capacity primary currents up to 4000 A with a 4000:5 transformation ratio
- Designed for secure DIN rail installation using screw termination methods
Applications
- Industrial power distribution systems requiring accurate current monitoring
- Electrical metering panels for high-current circuit analysis
- Protection relay circuits in heavy industrial infrastructure
Procurement Notes
Verify the specific ordering suffix against official Altech documentation to ensure the correct accuracy class and burden rating are selected. Confirm that the primary current rating of 4000 A aligns with the target application's load requirements. Check regional availability through authorized distributors, as supply status may vary by location. Ensure compatibility with standard DIN rail mounting configurations during system integration planning.
Selection Notes
Select this model when high-precision measurement is required for very high primary currents in industrial settings. The 0.5 accuracy class makes it suitable for billing and detailed energy monitoring rather than simple protection. Consider the 15 VA burden limit when calculating total connected load on the secondary side. Ensure the operating temperature range meets environmental conditions, typically spanning 0°C to +50°C for standard industrial environments.
Part Context
This component belongs to Altech's SPCT series of industrial current transformers. These devices are engineered for robust performance in demanding electrical environments. The series offers various ratios and accuracy classes to suit different measurement needs. The SPCT140 variant specifically addresses high-current applications where standard sensors would be insufficient. It represents a specialized solution for large-scale power management and monitoring tasks.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source data. Verify exact dimensional and electrical parameter matches before considering alternative models from other manufacturers. Ensure any replacement maintains the same 4000:5 ratio and 0.5 accuracy class to preserve system calibration integrity.
