MiCOM Railway Applications

Easergy™ MiCOM P138 - Overcurrent Protection Device for Rail Applications The Easergy MiCOM 30 series rail devices are dedicated to railway catenary protection. The Easergy MiCOM P138 specifically provides directional overcurrent protection for rail applications The Easergy MiCOM P138 enables a wide range of applications to protect supplies and catenaries in classic and autotransformer-fed (AT) systems. With easy connection to virtually all substation and catenary network management systems, it is enhanced by a complete range of backup protection and automation functions Easergy MiCOM P638 - Transformer Protection Device for Rail Applications Easergy MiCOM Px30 rail devices are dedicated to railway catenary protection. The Easergy MiCOM P638 provides transformer differential protection Easergy MiCOM P638 enables a wide range of applications to protect supplies and catenaries in classic and autotransformer-fed (AT) systems. With easy connection to virtually all substation and catenary network management systems, Easergy MiCOM P638 is enhanced by a complete range of backup protection and automation functions Easergy MiCOM P436 and P438 - Distance Protection Devices for Rail Applications Easergy MiCOM 30 series rail devices are dedicated to railway catenary protection. The Easergy MiCOM P436 provides catenary protection for classic and two-phase AT feeders. Easergy MiCOM P436 and Easergy MiCOM P438 enable a wide range of applications to protect supplies and catenaries in classic and autotransformer-fed (AT) systems. With easy connection to virtually all substation and catenary network management systems, the two models are enhanced by a complete range of backup protection and automation functions.
