CT-0050-D10

Overview

The Littelfuse CT-0050-D10 is a single-phase current sense transformer designed for industrial control applications. It features a donut mounting style with a 1-inch window and operates within 24VAC control circuits. The device provides a 50:5 current ratio, enabling precise monitoring of AC currents up to 50A. It includes bypass circuitry compatible with cooling anticipators having resistance values greater than or equal to 3000 ohms. This component supports the ordered operation of multiple loads, such as electric heating elements, ensuring reliable performance in quality protection scenarios.

Feature Summary

• Designed for operation in 24VAC control circuits
• Includes bypass circuitry for compatibility with high-resistance cooling anticipators
• Supports ordered running of multiple identical loads

Applications

• Single-phase pump monitoring
• Control circuits for electric heating elements
• Quality protection systems requiring current sensing

Procurement Notes

Verify that the application requires a 50:5 current ratio and a 1-inch window size. Confirm compatibility with 24VAC control circuits and ensure the connected cooling anticipator meets the minimum resistance requirement. Check regional shipping restrictions, as availability may be limited to specific sales areas. Ensure the donut mounting style fits the physical installation constraints of the equipment.

Selection Notes

Select this model when precise current sensing is required for single-phase AC loads in control environments. It is suitable for applications needing to monitor current levels up to 50A with a proportional output. Consider its compatibility with existing control circuit voltages and the need for bypass functionality if high-resistance anticipators are present. Evaluate the physical space available for a donut-style mount before finalizing the choice.

Part Context

This component belongs to the CT Series of current transformers from Littelfuse Inc. These devices are engineered for industrial use, focusing on accurate current monitoring and protection. The series offers various configurations to suit different load requirements and control circuit specifications, providing a robust solution for managing electrical loads in automated systems.

Replacement Considerations

Ensure any substitute part matches the 50:5 current ratio and 1-inch window dimension. Verify that the replacement supports 24VAC operation and includes similar bypass circuitry for high-resistance anticipators. Confirm that the new component maintains the donut mounting style and is suitable for single-phase applications.
