37025

Overview

The Simpson Electric 37025 is a current transformer designed to reduce high AC current signals to a standardized 5 amp AC output. It features screw terminals for secure electrical connections and flange mounting for chassis installation. The device operates within a frequency range of 50Hz to 400Hz, making it suitable for standard industrial power applications. It converts primary currents up to 1000A into secondary signals compatible with analog panel meters or digital indicators.

Feature Summary

• Reduces high AC current signals to a 5 amp AC signal for safe monitoring
• Converts AC current signals to 0-10 ACV signal for rectifier type meters
• Optimized for remote sensing of AC current signals where donut transformers are ineffective

Applications

• Remote sensing of AC current signals
• Use with analog and 5 amp AC digital indicators
• Low current measurement applications requiring precise signal conversion

Procurement Notes

Verify the specific primary current rating required for your application, as the 37025 model typically supports a 1000/5 Amp ratio. Confirm that the operating frequency falls within the 50Hz to 400Hz range. Ensure compatibility with downstream analog or digital panel meters expecting a 5A input. Check RoHS compliance status if environmental regulations apply to your project.

Selection Notes

Select this component when a compact, flange-mounted solution is needed for converting high primary currents to a standard 5A secondary signal. It is ideal for scenarios requiring isolation between the high-current circuit and the measuring instrument. Consider the physical dimensions of 96.01mm x 89.66mm for panel cutout requirements. Ensure the metering device accepts the specific output signal type provided by this transformer.
