KYMTS-63A 4P Manual Transfer Switch
The manual transfer switches 63A 4P provide safe changeover for three-phase + neutral AC systems.
Compact body, ergonomic I–0–II handle, copper contacts, DIN-rail or panel mounting.
IEC 60947-3 compliant, suitable for commercial, industrial, and PV/ESS applications.
Overview
The manual transfer switches (KYMTS-63A 4P) are designed for three-phase + neutral systems requiring secure and reliable source changeover. The 4-pole design switches L1/L2/L3/N simultaneously, ensuring complete isolation during manual I–0–II operation between utility, generator, or PV inverter sources.
For more models and selection details, refer to the Manual Transfer Switch landing page. In PV and ESS applications, the 4P unit is commonly paired with PV combiner boxes, circuit breakers, and DC fuses. Reference IEC standards and CE certification for compliance.

FAQ
What are manual transfer switches used for?
Manual transfer switches safely changeover loads between two power sources, such as utility and generator or PV inverter, with full pole isolation.
Why choose a 4P switch instead of 3P?
A 4P switch isolates the neutral in addition to all three phases, which many building standards require for safety during source transfer.
