The manual transfer switches 125A 4P provide full isolation of L1/L2/L3/N during changeover.
Ergonomic I–0–II handle, copper contacts, DIN-rail or panel mounting.
IEC 60947-3 compliant; ideal for commercial, industrial, and PV/ESS systems.
The manual transfer switches (KYMTS-125A 4P) are designed for three-phase + neutral AC systems that require reliable source changeover. The 4-pole configuration provides full isolation of L1/L2/L3/N during I–0–II switching between utility, generator, or PV inverter, ensuring maximum safety and compliance.
To compare full KYMTS series, see the Manual Transfer Switch landing page. In PV and ESS setups, the 4P unit integrates with PV combiner boxes, upstream circuit breakers, and DC fuses. Refer to IEC and CE certification for standards compliance.
