37034

Overview

The Simpson Electric 37034 is a split core current transformer designed for panel mounting. It features a turns ratio of 600:5, supporting primary currents up to 600 A and secondary outputs of 5 A. The device operates at frequencies of 50/60 Hz with an accuracy class of 0.5. Its rated burden is 6.25 VA. Physical dimensions include an overall height of 4.92 inches, depth of 2.85 inches, and an axial opening of 2.17 inches. Connection is facilitated via screw terminals.

Feature Summary

• Split core design allows installation without disconnecting conductors
• Screw terminal connection for secure wiring
• Rectangular window shape accommodates busbars or cables
• Class 0.5 accuracy ensures precise measurement

Applications

• Industrial power monitoring systems
• Electrical panel metering
• Energy management solutions
• Current sensing in distribution networks

Procurement Notes

Verify the specific accuracy class and burden rating requirements against the application needs before ordering. Confirm that the physical aperture size matches the conductor or busbar dimensions. Ensure the operating frequency aligns with the system's 50/60 Hz standard. Check for any specific mounting hardware requirements associated with panel installation.

Selection Notes

Select this model when a non-intrusive current measurement solution is required for high-current applications up to 600 A. The split core feature is essential for retrofits or installations where cable disconnection is impractical. Consider the 6.25 VA burden capacity to ensure compatibility with downstream meters or relays. Verify the rectangular window shape fits the available space and conductor geometry.

Part Context

This component belongs to the Simpson Electric 30000 series of split core current transformers. These devices are engineered for industrial environments requiring reliable current sensing. The series offers various ratios and burden ratings to suit different measurement scales. The 37034 specifically addresses high-current applications with its 600 A primary rating.

Replacement Considerations

Direct substitutes may include other Simpson Electric models within the same series with matching ratios. Cross-reference aperture sizes and burden ratings when considering alternatives from other manufacturers. Ensure the replacement maintains the Class 0.5 accuracy if precision is critical. Verify terminal types and mounting configurations for compatibility.
