Overview
The Simpson Electric 1298 is a donut-type current transformer designed for electrical measurement applications. It features a nylon construction with black coloring, providing impact and abrasive resistance suitable for demanding environments. The device supports a primary-to-secondary current ratio of 150/5 Amps, enabling accurate current sensing for metering or protection circuits. With physical dimensions of 4.5 inches in height and length, it offers a compact form factor for integration into panel boards or switchgear assemblies where space efficiency is required.
Feature Summary
- Donut core design for through-hole conductor installation
- Nylon housing provides impact and abrasive resistance
- Standard 150/5 Amp current transformation ratio
Applications
- Electrical panel metering systems
- Industrial switchgear current monitoring
- Protection relay input circuits
Procurement Notes
Verify the specific datasheet version for terminal configuration and burden requirements before ordering. Confirm that the 150/5A ratio aligns with the connected load range. Ensure the 4.5-inch aperture accommodates the target conductor size. Check for any regional compliance certifications required for the installation site.
Selection Notes
Select this model when a robust, non-invasive current sensing solution is needed for up to 150 Amps primary current. The nylon construction makes it suitable for harsh industrial conditions requiring durability against physical wear. Consider the 150/5A output compatibility with standard 5A secondary rated instruments.
Part Context
This component belongs to Simpson Electric's line of current transformers, which are used for stepping down high currents to measurable levels. The 1298 specifically addresses applications requiring durable, donut-style transformers that can withstand physical stress while maintaining accurate current transformation ratios for monitoring purposes.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing mounting hardware and wiring configurations if considering alternative models from other manufacturers.
