SPCT-140/100-1600/5A-VA15-CL0.5-CE

Overview

The SPCT-140/100-1600/5A-VA15-CL0.5-CE is a square type bus bar current transformer manufactured by Selec Controls USA Inc. It features a primary rating of 1600 A and a secondary output of 5 A, designed for frequencies between 50 Hz and 60 Hz. The unit has an outer diameter of 140 mm and an inner diameter of 100 mm to accommodate specific busbar dimensions. It carries a rated burden of 15 VA and maintains an accuracy class of 0.5. The device supports DIN rail and panel mounting configurations.

Feature Summary

• Square bus bar design accommodating 140 mm outer and 100 mm inner diameters
• High precision measurement with Class 0.5 accuracy rating
• Versatile mounting options supporting both DIN rail and panel installation

Applications

• Electrical energy metering systems
• Industrial power distribution monitoring
• Current sensing in switchgear assemblies

Procurement Notes

Verify the physical aperture dimensions (140 mm OD / 100 mm ID) against the installed busbar size to ensure proper fit. Confirm that the connected burden does not exceed the 15 VA rated limit to maintain Class 0.5 accuracy. Ensure the operating frequency matches the system's 50 Hz or 60 Hz requirement. Check for CE marking compliance if required by local regulations.

Selection Notes

Select this model when a high-current primary rating of 1600 A is required with a standard 5 A secondary output. The large aperture accommodates substantial busbars where split-core alternatives are impractical. Choose this variant for applications demanding strict accuracy standards under moderate burden conditions. Consider the mounting style requirements before finalizing the procurement decision.

Part Context

This component belongs to the SPCT series of square type bus bar current transformers from Selec Controls. These devices are engineered for non-invasive current measurement in fixed electrical installations. The series provides reliable isolation and signal transformation for metering and protection circuits in industrial environments.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing busbar dimensions and mounting hardware before considering alternative models.
