CR9380-ACA

Current Sensors Overview

The CR9380-ACA is a bidirectional AC current switch from the CR9380 series, designed for on-off indication of current flow. It features a split core design with a single pass-through window measuring 0.39 inches. The device operates at frequencies between 50Hz and 400Hz and has a maximum sensing current of 100A. It utilizes an SCR output for switching AC loads and includes reverse output polarity protection. The unit is self-powered and fully isolated, intended for continuous operating currents above 350mA.

Current Sensors Feature Summary

• Self-powered fixed set-point operation for continuous current monitoring
• Fully isolated construction with reverse output polarity protection
• Split core design allowing installation without breaking the conductor
• Solid-state SCR output suitable for direct connection to PLCs or relays

Current Sensors Applications

• Industrial machinery current flow monitoring
• PLC input signaling for AC circuits
• Electrical panel status indication
• Motor control circuit supervision

Current Sensors Procurement Notes

Verify that the application current exceeds the 350mA minimum threshold to ensure proper output activation. Confirm compatibility with the system frequency range of 50Hz to 400Hz. Ensure appropriate clamping diodes are provided if connecting to inductive DC loads, though this model is AC-specific. Check for mounting case requirements as the base unit may require separate housing.

Current Sensors Selection Notes

Select this component when a low-cost, self-powered solution is required for AC current detection. The split core architecture simplifies retrofitting into existing busbars or cables. The SCR output provides robust switching capability for AC applications. Consider the 100A maximum rating against peak load requirements to prevent saturation or damage during transient events.
