Description

Manual Transfer Switch (MTS) – 4+4 Pole, 63A (YRO YMTS-63) | 3-Phase Changeover Switch

Take full manual control of your three-phase power switching with the YRO YMTS-63 4+4 Pole Manual Transfer Switch (MTS) — a heavy-duty three-phase changeover switch engineered for safe, reliable manual switching between two three-phase power sources such as mains and generator, or mains and solar inverter. Compliant with IEC 60947-3 and rated AC-22A at 230V 50/60Hz, this MTS delivers complete 4+4 pole isolation across all live and neutral conductors simultaneously — making it the dependable, no-electronics solution for three-phase installations where simplicity, clarity, and long service life are the priority.

The YMTS-63 features a three-position toggle handle — Position I (Source 1 active), Position O (Off/Isolated), and Position II (Source 2 active) — with a positive mechanical lock at each position to prevent accidental or unintended switching. The 4+4 pole configuration provides complete dual-source isolation across all three phases and neutral at the same time, ensuring absolutely no backfeed between sources at any point during changeover.
