Schneider Electric MiCOM P436 MiCOM P438 Numerical Rail Catenary Distance Protection Relay
Schneider Electric MiCOM P436, MiCOM P438 Numerical Rail Catenary Distance Protection Relay is designed to protect railway traction power systems and catenary feeders in both conventional and autotransformer-fed (AT) railway networks. It provides dependable distance protection together with backup protection and automation functions, helping maintain reliable operation of railway power infrastructure.
The MiCOM P436, MiCOM P438 is built for railway applications where fast fault detection and selective isolation are essential. It supports a wide range of protection schemes and can be adapted to different operating conditions through four independent setting groups. This allows the relay to be configured for changing feeder arrangements and alternative power supply conditions without complex modifications.
The relay also integrates easily with railway substations and catenary management systems through multiple communication interfaces. InterMiCOM teleprotection enables direct communication between protection devices, while the modular design allows installation in rack, flush-mounted or wall-mounted panels.
