Overview
The Phoenix Contact 2277857 is a window-type current transformer from the PACT MCR-V2 series, designed for measuring high alternating current levels. It features a primary current rating of 200 A AC and a secondary output of 5 A. The unit has a rated power of 7.5 VA and operates within a frequency range of 50 Hz to 60 Hz. It supports DIN rail and panel mounting styles, with a bore diameter of 28 mm.
Feature Summary
- Window-type design allows direct measurement of busbars or cables without breaking the circuit
- Provides isolated secondary current signal for monitoring and control applications
- Supports standard DIN rail and panel mounting configurations
Applications
- Industrial energy monitoring systems
- Electrical protection relay circuits
- Power quality analysis equipment
Procurement Notes
Verify that the required primary current does not exceed 200 A AC to ensure accurate transformation ratios. Confirm that the operating frequency aligns with the 50 Hz to 60 Hz specification. Ensure the conductor passing through the 28 mm bore fits securely to maintain measurement integrity. Check compatibility with downstream 5 A input devices in the control system.
Selection Notes
Select this component when a non-intrusive method for measuring up to 200 A AC is required. The 28 mm bore size accommodates standard industrial busbars or thick cables. Consider the 7.5 VA burden capacity when connecting multiple secondary loads. Verify that the 5 A output matches the input requirements of the connected metering or protection device.
Part Context
This part belongs to the PACT MCR-V2 series, which focuses on current sensing and conditioning. The series provides reliable isolation between primary high-current lines and secondary low-voltage control circuits. It complements other signal processing modules in industrial automation setups.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify exact bore dimensions and output ratings before considering alternative models.
