Frequently Asked Questions
What is a PC Class Automatic Transfer Switch?
A PC Class Automatic Transfer Switch (ATS) is a switching device specifically designed to transfer electrical loads between the normal power source and the standby power source. It is intended for reliable power transfer and does not provide overload or short-circuit protection. Appropriate circuit breakers or fuses should be installed upstream for system protection.
How do I choose the correct ATS rated current?
The ATS rated current should be equal to or greater than the maximum operating current of the connected load. Load type, motor starting current, ambient temperature, and future capacity expansion should also be considered to ensure safe and reliable operation.
Can the JUQ5 ATS work with a diesel generator?
Yes. The JUQ5 PC Class Automatic Transfer Switch is suitable for applications requiring automatic transfer between utility power and a diesel generator. It is widely used in commercial buildings, industrial facilities, hospitals, data centers, and other backup power systems.
What is the difference between a PC Class ATS and a CB Class ATS?
A PC Class ATS uses a dedicated switching mechanism specifically designed for transferring power between two sources, while a CB Class ATS is typically built with circuit breakers and can also provide overload and short-circuit protection. PC Class ATS units are generally more compact and optimized for reliable power transfer.
Does JUTRION provide OEM and ODM services?
