ATO-50-B225-D10

Current Sense Transformers Overview

The ATO-50-B225-D10 is a split-core current transformer manufactured by LEM USA Inc., designed for measuring alternating currents up to 50A. It operates within a frequency range of 50Hz to 60Hz and features a chassis mount installation type. The device utilizes a split-core design, allowing for non-intrusive installation around primary conductors without breaking the circuit. This component is suitable for applications requiring basic insulation and compliance with CAT III PD2 safety standards.

Current Sense Transformers Feature Summary

• Split-core construction enables easy installation around existing busbars or cables
• Designed for AC current measurement in power distribution systems
• Supports chassis mounting for secure integration into electrical panels

Current Sense Transformers Applications

• AC current monitoring in industrial power distribution panels
• Energy metering applications requiring 50Hz to 60Hz measurement
• Safety compliance testing for equipment rated up to 600V CAT III

Current Sense Transformers Procurement Notes

Verify that the required primary conductor diameter fits within the split-core aperture of the ATO-50-B225-D10 before ordering. Confirm that the application environment does not exceed the specified voltage isolation limits for CAT III PD2. Ensure that the mounting hardware provided is compatible with the intended chassis panel thickness. Check for any specific torque requirements during installation to maintain signal integrity and mechanical stability.

Current Sense Transformers Selection Notes

Select this model when a non-invasive solution for 50A AC current sensing is required at standard utility frequencies. It is appropriate for retrofits where opening the primary circuit is not feasible. Consider the split-core mechanism if frequent reconfiguration of the primary conductor is anticipated. Ensure the system architecture can accommodate the output characteristics typical of passive current transformers.

Current Sense Transformers Part Context

This part belongs to the ATO series of current sense transformers from LEM USA Inc. The series includes various ratings such as 10A, 15A, 16A, 20A, 30A, 32A, 60A, 63A, and 75A. The B225 suffix typically denotes specific physical dimensions and core material properties common across the series. These sensors are generally used in conjunction with external burden resistors or signal conditioning circuits.
