GENERAL ELECTRIC P54381NC6M0760M | MiCOM Agile P543 Protection Relay

📝 Product Description

The GE P54381NC6M0760M is a MiCOM Agile P543 protection relay from the P40 platform, designed for transmission and sub-transmission line protection applications. The P543 family combines high-speed current differential protection with distance protection and directional earth-fault functions, providing protection, control, monitoring, and recording capabilities for overhead lines and cable systems. GE documentation identifies the P543 as a single-circuit-breaker application within the P54 family.

The relay can interface with longitudinal communications channels between line terminals and can be configured with conventional CT/VT inputs or, for applicable variants, IEC 61850-9-2LE sampled-value inputs. The exact protection, I/O, communication, and power-supply configuration is determined by the complete ordering code, so the full P54381NC6M0760M designation should be matched before replacement or system integration.

❓ Common Questions & Answers

Q: What is the P54381NC6M0760M?
A: It is a GE MiCOM Agile P543 protection relay within the P40 platform.

Q: What is the primary application of the P543?
A: The P543 is designed for current differential protection of overhead lines and cables, with additional distance and directional earth-fault protection functions depending on the configuration.

Q: Is the P543 suitable for transmission systems?
A: Yes. GE describes the P543/P544/P545/P546 range as transmission-class protection relays for HV, EHV, and UHV applications.

Q: Does the P543 support distance protection?
A: Applicable P543 variants support subcycle distance protection in addition to current differential protection.

Q: Does this exact model support IEC 61850?
A: IEC 61850-9-2LE sampled-value options are available within the P54 family, but the exact interface must be confirmed from the complete ordering code and physical unit.

Q: What is the listed condition?
A: The referenced listing specifies New – Open Box.

Q: Can it be used as a direct replacement for another P543?
A: Not automatically. The complete model code, hardware revision, CT/VT configuration, digital I/O, communication interfaces, power supply, and firmware should be compared before replacement.
