Schneider Electric Easergy MiCOM P638 Numerical Railway Protection Relay

Schneider Electric Easergy MiCOM P638 Numerical Railway Protection Relay is designed to protect railway power supply systems, including catenary networks and traction substations. It provides dependable protection for both conventional and autotransformer-fed (AT) railway systems, making it suitable for modern rail infrastructure where reliable fault detection and uninterrupted power supply are essential.

The MiCOM P638 combines protection, automation and communication functions in a single relay. It supports a wide range of railway protection applications while allowing users to adapt the relay to different operating conditions through four independent setting groups. This flexibility makes it suitable for railway networks with changing feeding arrangements or multiple operating modes.

The relay also integrates easily with substation and catenary management systems through multiple communication interfaces. InterMiCOM teleprotection enables fast exchange of binary information between line ends, while its modular design allows simple installation in new or existing railway protection panels.
