ACUCT-H040-20:333-10M

Current Sense Transformers Overview

The ACUCT-H040-20:333-10M is a current sense transformer designed for monitoring AC current in electrical systems. It features a hinged split-core design with a 0.4-inch (10.2 mm) aperture, allowing for installation around existing conductors without disconnecting the circuit. The device is rated for a maximum monitored current of 20 A and operates within a frequency spectrum of 50 Hz to 60 Hz. It provides a secondary output of 333 mV at the full-rated primary current. The unit includes 10-meter leads for connection to sensing equipment and has a maximum installed height of 1.654 inches (42.00 mm).

Current Sense Transformers Feature Summary

• Hinged split-core construction enables non-intrusive installation around live conductors.
• Provides isolated voltage output proportional to the monitored AC current.
• Designed for standard power line frequencies of 50 Hz and 60 Hz.

Current Sense Transformers Applications

• AC current monitoring in industrial control panels
• Energy management and power quality analysis systems
• Electrical protection relay input circuits

Current Sense Transformers Procurement Notes

Verify that the conductor diameter fits within the 0.4-inch aperture before procurement. Confirm that the required lead length of 10 meters meets the installation distance between the sensor and the measurement device. Ensure the system frequency matches the 50/60 Hz operational range. Check that the 333 mV output signal is compatible with the input requirements of the connected meter or PLC module.

Current Sense Transformers Selection Notes

Select this model when a split-core solution is required for retrofitting existing wiring. Choose based on the 20 A rating if the monitored load does not exceed this limit. Consider the 10-meter lead length as a fixed specification; shorter or longer leads are not available for this specific part number. Ensure the physical space allows for the 1.654-inch height constraint.

Current Sense Transformers Part Context

This component belongs to the ACUCT-H040 series of current transformers from Automation Components, Inc. The series utilizes a hinged split-core architecture to facilitate easy mounting. Variations in the series typically differ by primary current rating and lead length, while maintaining similar core geometry and output characteristics for standardized integration into power monitoring setups.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 20 A rating, 333 mV output, and 0.4-inch aperture. Verify that any alternative split-core transformer supports the same 50/60 Hz frequency range. Ensure the replacement unit offers compatible lead lengths or can be adapted to the existing 10-meter cable run without signal degradation.
