MODEL 18-600

Current Sense Transformers Overview

The MODEL 18-600 is a general-purpose wire lead current transformer manufactured by CR Magnetics Inc. It features a solid core design with an internal diameter of 0.55 inches, accommodating conductors up to that size. The unit incorporates 605 turns and supports a maximum input current range of 100 Arms. Electrical specifications include a maximum RMS voltage of 5.0 V. The device operates within a frequency range of 50 Hz to 1 kHz. Physical dimensions are 1.331 inches in length, 0.520 inches in width, and a maximum seated height of 1.488 inches. Termination is achieved via wire leads.

Current Sense Transformers Feature Summary

• Non-invasive measurement capability using a solid core design for isolated current sensing
• General-purpose construction suitable for standard industrial monitoring applications
• Wire lead termination style facilitating direct circuit integration

Current Sense Transformers Applications

• Power transmission and distribution systems
• High-power motor control cabinets
• Current sensing in electrical monitoring equipment

Current Sense Transformers Procurement Notes

Verify the specific manufacturer designation when sourcing, as distributor listings may occasionally conflate similar part numbers from different vendors such as Bourns. Confirm that the required component is the CR Magnetics current transformer rather than a ferrite chip bead or other passive element. Ensure the order specifies the wire lead termination style and solid core configuration to match the intended installation requirements.

Current Sense Transformers Selection Notes

Select this model when non-contact current measurement is required for conductors fitting within a 0.55-inch inner diameter. The 100 Arms rating defines the operational limit for accurate sensing. Consider the 5.0 Vmax RMS specification for downstream signal conditioning compatibility. The wire lead format is appropriate for applications where surface mount options are unsuitable or where robust mechanical connection is preferred over PCB mounting.

Current Sense Transformers Part Context

This component belongs to the Model 18 series of remote electrical current indicators produced by CR Magnetics. The series is characterized by low-cost, non-contact measurement solutions. Related models in the family may offer surface mounting brackets, but the MODEL 18-600 specifically utilizes wire leads for connection. It serves as a dedicated sensor for detecting alternating current levels in power infrastructure.

Current Sense Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 605 turn count, 0.55-inch ID, and 100 Arms rating with alternative current transformers from other manufacturers.
