Q5M PC-class Isolated Automatic Transfer Switch 100A-1600A for Industrial & Generator system
Q5M series is a PC-class, isolated-type automatic transfer switch (ATSE) designed for AC 50/60Hz, rated voltage up to 400V systems. It is used for automatic switching between normal power and standby power (mains-mains or mains-generator) to ensure uninterrupted power supply.
As an isolated load switch type ATS without overcurrent protection function, Q5M relies on upstream protection devices. It features reliable electromechanical interlock, obvious isolation indication, high short-time withstand current, and long mechanical life. It is widely used in data centers, hospitals, banks, high-rise buildings, industrial plants, and generator supporting projects.
Model Explanation
Q5M – □□□ / □P
- Q5M: Series code (PC-class isolated ATS)
- □□□: Rated current (100A, 160A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A)
- □P: Poles (2P, 3P, 4P)
Key Features
- True PC-class isolated structure, built with double load switches, no built-in circuit breaker
- Obvious on/off indication and safety isolation function with lockable position
- High short-time withstand current, strong anti-short-circuit impact capability
- Integral electromechanical interlock ensures no parallel of two power sources
- Auto / manual dual operation; emergency manual forced zero-position available
- Conversion time: ≤ 0.2s~3s (customizable)
- Wide current range: 100A to 1600A, poles 2P/3P/4P optional
- Compliant with IEC 60947-6-1 & GB/T 14048.11
