SID-3YLE

Phase Selection Device

SID-3YLE is a high-performance phase selection reclosing controller, specifically designed to suppress transient impacts caused by switching nonlinear loads.

It features precise phase angle control, supports phase-separated or linked breaker operations, and incorporates advanced algorithms such as online transformer residual magnetism calculation and adaptive breaker timing correction to ensure optimal closing angles.

With an independent dual-system control architecture, a single device can control two breakers simultaneously, and it supports online switching of multiple application modes. The controller is compatible with Modbus and IEC 61850 MMS protocols and integrates rich waveform recording and event logging functions, making it an ideal solution for safe and accurate reclosing of critical equipment.
