2277611

Overview

The Phoenix Contact 2277611 is a bus-bar current transformer designed for measuring alternating currents. It features a primary current rating of 75 A AC and a secondary current rating of 5 A AC. The device operates within a frequency range of 50 Hz to 60 Hz and maintains an accuracy class of 1. Its rated power is specified at 2.5 VA. This component utilizes a non-invasive solid core design, allowing it to be mounted directly onto bus-bars without interrupting the circuit.

Feature Summary

• Non-invasive solid core design for direct bus-bar mounting
• Accurate measurement of alternating currents with class 1 precision
• Compatible with standard 50 Hz to 60 Hz AC power frequencies

Applications

• Industrial electrical panel monitoring
• Energy management systems
• Power distribution network measurement

Procurement Notes

Verify that the required primary current does not exceed 75 A AC and the load impedance remains within the 2.5 VA limit. Confirm compatibility with 50/60 Hz systems. Ensure the bus-bar dimensions accommodate the solid core aperture. Check for accuracy class 1 requirements in your specific metering application before finalizing the order.

Selection Notes

Select this model when a non-invasive solution for 75 A AC circuits is needed. It is suitable for applications requiring class 1 accuracy. Consider the 2.5 VA burden capacity when connecting secondary devices. Ensure the installation environment supports DIN rail or bus-bar mounting configurations as specified by the mechanical design.
