Description
🔹 Product Overview
The Schneider Electric MiCOM P442 P44231AB6M0400K is a numerical distance protection relay from the MiCOM P44x family. The P442 is designed for high-performance protection of overhead transmission lines and cables, with distance protection functions used to detect and isolate electrical faults according to the configured protection scheme. Schneider Electric identifies the P44x family as a high-performance distance-protection range covering models including P441, P442, P443, P444 and other variants.
The P442 platform combines protection, measurement, control and communication functions within a programmable numerical relay. Depending on the exact hardware and configuration, the relay can incorporate multiple current and voltage inputs, programmable opto-isolated inputs, output relays, watchdog supervision and communication interfaces. The exact I/O and communication arrangement must be verified against the complete P44231AB6M0400K ordering code and the relay nameplate before installation.
P44231AB6M0400K
This unit is suitable for maintenance, replacement, refurbishment and spare-parts requirements in compatible medium- and high-voltage protection systems. Schneider Electric continues to provide technical documentation for the P44x range, including P442/P444 technical manuals and IEC 61850 protocol documentation.

❓ FAQ
Q1: What is the exact model?
The unit is identified as MiCOM P442, with complete ordering code P44231AB6M0400K.
Q2: What is the primary function of the P442?
The P442 is a numerical distance protection relay intended for overhead-line and cable protection applications.
Q3: Is every P442 configured the same way?
No. MiCOM P442 ordering codes specify different hardware and functional configurations. The complete P44231AB6M0400K code should therefore be matched when replacing an existing relay.
Q4: Does the P442 support communications?
P44x relays support communication options, with IEC 61850 documentation available for applicable configurations. The exact communication interface should be confirmed from the individual relay’s ordering code and rear-panel configuration.
Q5: What should be checked before installation?
Verify the complete ordering code, auxiliary supply, CT/VT input ratings, I/O configuration, communication interface, firmware, protection settings and existing protection-system requirements before commissioning.
