7SFT-122

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc. model 7SFT-122 is a single-phase current transformer designed for indoor panel mounting applications. It features a window-type construction with a primary-to-secondary current ratio of 1200:5. The device operates at frequencies ranging from 50Hz to 400Hz and supports a burden capacity of 35VA at 600V. It provides 10kV Basic Insulation Level (BIL) protection and is rated for 60Hz operation in standard configurations.

Current Sense Transformers Feature Summary

• Window-type construction for non-invasive conductor installation
• High insulation rating ensuring safety in electrical systems
• Supports variable frequency operation up to 400Hz

Current Sense Transformers Applications

• Indoor electrical panel installations
• Current sensing for metering equipment
• Protection relay circuits

Current Sense Transformers Procurement Notes

Verify the specific frequency rating required by your application, as sources indicate both 60Hz and 50-400Hz capabilities. Confirm that the 1200:5 ratio matches your system requirements. Ensure the 35VA burden capacity is sufficient for connected instruments. Check for any specific ANSI or non-ANSI rating designations relevant to your region's standards before finalizing the order.

Current Sense Transformers Selection Notes

Select this component when a 1200:5 ratio is needed for indoor current monitoring. The 10kV BIL makes it suitable for higher voltage environments within panels. Consider the 35VA load limit when connecting multiple meters or relays. The window type allows for easy retrofitting around existing busbars or cables without breaking the circuit.

Current Sense Transformers Part Context

This unit belongs to the Model 7 series of current transformers manufactured by Sifam Tinsley, also marketed under Crompton Instruments. These devices are precision instrumentation components used for accurate current measurement and isolation in industrial and commercial power distribution systems.

Current Sense Transformers Replacement Considerations

Direct substitutes include part numbers such as CI-7SFT-122 from Crompton Instruments. Verify that replacement units maintain the 1200:5 ratio, 35VA burden, and 10kV BIL specifications to ensure compatibility with existing panel setups.
