The CNC YCQ3B-63 is an automatic transfer switch (ATS) designed to switch between two power sources, typically a main power supply and a backup source like a generator.  Available in both 2-pole and 4-pole configurations, it ensures a continuous power supply to critical loads by automatically transferring to the backup source when the main power fails.  This switch is rated for 63A and is commonly used in applications where an uninterrupted power supply is essential.
