Current Sensors Procurement Notes

Verify the specific model suffix against official CR Magnetics documentation to confirm the exact current rating and output configuration. Ensure the procurement channel sources genuine components from authorized distributors to guarantee compliance with UL 61010B-1 and IEC 61010-1 safety standards. Cross-reference technical specifications with the latest datasheet before integration.

Current Sensors Selection Notes

Select this component when measuring AC currents with complex waveforms requiring True RMS accuracy. The three-element architecture distinguishes it from single or two-element variants in the CR4100 series. Consider the 15A input range and 20Hz-5kHz bandwidth for compatibility with industrial heating and motor control systems requiring precise harmonic analysis.

Current Sensors Part Context

This part belongs to the CR4100 Series of True RMS Current Transducers by CR Magnetics Inc. The series includes single, two, and three-element configurations tailored for various input ranges. The CR4170 variant specifically utilizes a three-element solid core design to enhance performance in demanding environments involving chopped waves and phase-fired controls.

Current Sensors Replacement Considerations

CR4150-15: Two-element variant with identical 15A rating but different internal architecture. CR4170-50: Same three-element design but rated for 50A input. Verify window size and mounting requirements when substituting within the CR4100 family.
