SPCT 50/30 100/5 A VA 1 CL 1-CU-ROHS

Current Sense Transformers Overview

The SPCT 50/30 100/5 A VA 1 CL 1-CU-ROHS is a non-invasive solid core current sense transformer manufactured by Selec Controls USA Inc. Designed for bus bar applications, this instrument transformer supports primary currents up to 100 A with a secondary output of 5 A. It operates within a frequency range of 50 Hz to 60 Hz and features a Class 1 accuracy rating with a 1 VA burden capacity. The unit is engineered for DIN rail mounting, providing a compact solution for electrical monitoring systems requiring precise AC current measurement without circuit interruption.

Current Sense Transformers Feature Summary

• Non-invasive solid core design enables installation around existing bus bars without breaking the conductor
• Class 1 accuracy rating ensures reliable performance for standard metering and protection applications
• DIN rail mounting configuration facilitates easy integration into control panels and switchgear assemblies

Current Sense Transformers Applications

• AC current monitoring in industrial distribution panels
• Energy metering systems requiring 100 A primary input
• Electrical protection circuits utilizing 5 A secondary signals

Current Sense Transformers Procurement Notes

Verify that the required primary current matches exactly 100 A and the secondary output is 5 A. Confirm the application frequency is strictly 50 Hz or 60 Hz. Ensure the mounting environment supports DIN rail installation. Check that the system burden does not exceed 1 VA to maintain Class 1 accuracy. Validate that the solid core design accommodates the specific bus bar dimensions of the target installation.

Current Sense Transformers Selection Notes

Select this component when a non-invasive measurement method is required for 100 A AC lines. The solid core construction eliminates the need for conductor splitting during installation. Choose this model if DIN rail compatibility is necessary for panel layout optimization. The Class 1 accuracy is suitable for general metering rather than high-precision laboratory use. Consider alternative ratios if the primary current exceeds 100 A or if different secondary outputs are needed.

Current Sense Transformers Part Context

This part belongs to the SPCT series of current transformers from Selec Controls USA Inc., which offers various primary current ratings including 75 A, 80 A, 125 A, 200 A, and 250 A. All models in this series share similar non-invasive solid core designs and DIN rail mounting capabilities. The series provides standardized 5 A secondary outputs with varying accuracy classes and burden capacities to suit different application requirements.

Current Sense Transformers Replacement Considerations

Direct substitutes include other variants within the same SPCT series such as SPCT 50/30 75/5 A, SPCT 50/30 80/5 A, SPCT 50/30 125/5 A, SPCT 50/30 200/5 A, and SPCT 50/30 250/5 A, provided the primary current rating aligns with the application needs. Cross-manufacturer replacements require verification of physical dimensions, mounting style, accuracy class, and electrical characteristics.
