ECSJ402SP

Current Sensors Overview

The Eaton Electrical ECSJ402SP is a CurrentWatch Series AC current switch designed for monitoring electrical loads up to 200A. It features an open-loop split core sensor with a response time ranging from 40 ms to 120 ms and operates within a frequency range of 6 Hz to 100 Hz. The device utilizes a normally open output contact rated for 1A at 240VAC, housed in a UL94 V0 flammability-rated plastic enclosure. It employs screw terminal connections and includes electronic proof of flow functionality.

Current Sensors Feature Summary

• Monitors AC current loads using a split core design without direct electrical connection to the primary circuit
• Provides isolated solid-state relay output with normally open configuration for safe switching
• Enclosed in UL94 V0 rated plastic housing for enhanced fire safety compliance

Current Sensors Applications

• Electronic proof of flow verification in industrial systems
• Conveyor belt motor monitoring and control
• Lighting circuit status indication
• Fan and pump operational tracking
• Critical motor protection circuits

Current Sensors Procurement Notes

Verify that the specific part number matches the required current rating and voltage specifications for your application. Confirm the enclosure material meets your environmental requirements. Ensure the response time aligns with your system's timing constraints. Check for any specific mounting or wiring instructions provided in the official documentation before installation.

Current Sensors Selection Notes

Select this model when monitoring AC currents up to 200A with a normally open output is required. Consider the 40-120 ms response time for compatibility with your control logic. The split core design allows for easy installation around existing conductors. Verify that the 240VAC contact rating suits your load switching needs.

Current Sensors Part Context

This component belongs to the Eaton CurrentWatch ESCJ Series, which specializes in AC current switches. The series offers various models tailored for different current ranges and output configurations. The ECSJ402SP specifically targets applications requiring reliable monitoring of moderate to high AC currents with simple switching capabilities.

Current Sensors Replacement Considerations

Consult Eaton Electrical's official cross-reference guides for verified substitute part numbers. Ensure any replacement maintains the same current rating, voltage limits, and response time characteristics. Verify compatibility with existing mounting hardware and wiring configurations.
