GFM25CT

Current Sense Transformers Overview

The GFM25CT is a neutral current transformer designed for use with PowerPact H, J, and L-frame circuit breakers. It functions as an accessory to detect ground faults by monitoring the neutral conductor. The device provides a secondary output signal proportional to the primary current, enabling connection to protective relays or monitoring equipment. It is engineered to meet specific safety and performance standards for electrical distribution systems.

Current Sense Transformers Feature Summary

• Designed specifically as a neutral current transformer for PowerPact H, J, and L-frame circuit breakers
• Provides accurate current sensing for ground fault protection applications
• Constructed to comply with relevant international safety and performance standards

Current Sense Transformers Applications

• Ground fault detection in electrical distribution panels
• Integration with protective relay systems for circuit breakers
• Neutral current monitoring in industrial power distribution networks

Current Sense Transformers Procurement Notes

Verify compatibility with specific PowerPact breaker frame types (H, J, or L) before procurement. Confirm that the application requires a neutral current transformer rather than a phase current transformer. Ensure the installation environment meets the operational temperature and humidity specifications defined in the official datasheet. Check for any required mounting hardware or accessories not included in the base unit package.

Current Sense Transformers Selection Notes

Select the GFM25CT when ground fault protection is required for PowerPact H, J, or L-frame breakers. This component is suitable for applications needing precise neutral current measurement. Consider the rated primary current and accuracy class requirements of the connected monitoring devices. Evaluate space constraints within the breaker panel to ensure proper fitment and wiring access.

Current Sense Transformers Part Context

The GFM25CT belongs to the Square D by Schneider Electric PowerPact accessory line. It complements the main circuit breaker units by adding advanced protection capabilities. This part is distinct from standard phase current transformers, focusing exclusively on neutral conductor monitoring. It supports modern electrical safety protocols in commercial and industrial settings.

Current Sense Transformers Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Verify if existing inventory includes compatible variants from the same PowerPact accessory series. Consult official Schneider Electric documentation for any updated replacement recommendations or superseded part numbers.
