Overview
The Weidmüller 2420960000 is a closed current transformer designed for precise measurement of load current consumption using RMS value methods. It features a primary current rating of 150 A and a maximum secondary current of 5 A. The device supports a burden load of 5 VA and maintains a tolerance class of 1. Designed for DIN rail mounting, it incorporates an asymmetrical cable feed-through mechanism to ensure accurate signal transmission in industrial electrical engineering applications.
Feature Summary
- Closed design for precise RMS-based current consumption measurement
- Asymmetrical cable feed-through configuration
- DIN rail mounting style for secure installation
Applications
- Industrial electrical engineering systems
- Automation process control engineering
- Signal processing circuits requiring current monitoring
Procurement Notes
Verify the specific ordering suffix CMA-31-150-5A-5VA-1 matches the required technical specifications before purchase. Confirm that the 150 A primary current and 5 VA load ratings align with the target application's electrical parameters. Ensure compatibility with existing DIN rail infrastructure and check for any regional tariff implications if shipping to the United States.
Selection Notes
Select this component when a closed current transformer with a 150 A primary rating is required for high-precision RMS measurements. The 5 A secondary output and 5 VA burden capacity suit standard industrial instrumentation. The asymmetrical feed-through design simplifies wiring integration within confined control panels compared to symmetrical alternatives.
Part Context
This part belongs to the Weidmüller current transformer series, specifically categorized under electric engineering and automation signal processing components. It serves as a critical interface for converting high primary currents into measurable secondary signals for downstream monitoring devices within industrial control environments.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Users must verify exact parameter matching if considering alternative manufacturers.
