Overview
The CR7SFT-122 is a commercial-grade AC current transformer manufactured by CR Magnetics Inc. It features an input range of 0 to 1200 AAC and an output range of 0 to 5AAC. The device utilizes a mounting case with two #8-32 terminals and has a 2.5-inch inner diameter. This component is designed for chassis mounting applications within the CR series product line.
Feature Summary
- Commercial grade construction for general industrial use
- Dual terminal configuration using standard #8-32 hardware
- Designed for direct chassis mounting integration
Applications
- Industrial power monitoring systems
- Electrical distribution panel instrumentation
- Current sensing in commercial machinery
Procurement Notes
Verify that the specific order matches the CR7SFT-122 part number exactly, as suffixes may indicate different electrical ratings or mechanical configurations. Confirm RoHS compliance status if required by project specifications. Ensure the receiving facility can accommodate the physical dimensions and terminal spacing defined in the official datasheet before finalizing procurement.
Selection Notes
Select this model when a 1200A primary current rating and 5A secondary output are required for commercial applications. Consider the 2.5-inch ID for conductor size compatibility. Evaluate the chassis mount style against available panel space. Compare against other CR series variants if higher precision or different insulation classes are necessary for the specific operational environment.
Part Context
This component belongs to the CR Magnetics Inc. CR series of current transformers. These devices are engineered for robust performance in commercial environments. The series provides reliable signal conversion for monitoring AC currents. The CR7SFT-122 represents a specific configuration within this broader family of sensors and transducers.
Replacement Considerations
Consult official substitution lists for compatible models with matching electrical parameters. Verify that any alternative part maintains the same 1200A input and 5A output ratios. Ensure mechanical compatibility regarding the 2.5-inch ID and mounting method before swapping components.
