FAQ
What is a 3 pole manual transfer switch?
It is a device that switches three-phase loads between utility and generator or inverter, ensuring continuity and preventing back-feeding.
When should I use a 3P instead of 4P?
A 3P is used when only the three phases require switching. A 4P is required if neutral isolation is also needed by code or system design.
Where can I compare KYMTS models?
