Q6 Molded Case Intelligent CB-Class Automatic Transfer Switch (ATS) High Reliability 100A-1250A
Q6 series is a compact molded case intelligent CB-class automatic transfer switch (ATSE), designed for AC 50/60Hz, rated voltage up to 400V low-voltage power systems. It realizes automatic or manual switching between normal mains power and backup power (generator/dual mains) to ensure uninterrupted power supply for critical loads.
Adopting an integrated molded case structure with built-in circuit breaker, Q6 integrates overcurrent, short-circuit protection and automatic transfer function in one unit. It features reliable mechanical & electrical interlock, compact size, easy installation, and intelligent control logic, widely used in residential, commercial, small industrial and emergency power supply scenarios.
