Features Versatile Product Structure: Composed of 2 miniature circuit breakers, auxiliary and alarm contacts, a mechanical interlocking transmission device, and a controller, ensuring a comprehensive and efficient setup. Seamless Power Transfer: Automatically switches load circuits from one power supply to another during power failure, guaranteeing uninterrupted power for essential equipment. Reliable Single Motor Drive: Operates with a single motor drive, delivering stability, quiet , and high changeover reliability through mechanical and electrical interlocking mechanisms. Enhanced Circuit Protection: Equipped with short circuit, overload, undervoltage protection, fire protection, dual output, and closing signal functions for safe and secure . Wide Applications: Especially suitable for lighting and small motor control equipment in various commercial settings such as office buildings, shopping malls, banks, stations, and hospitals. Features: 1、Product Structure: Composed of 2 miniature circuit breakers and their accessories (auxiliary contact, alarm contact), mechanical interlocking transmission device, controller, etc. 2、Working Principle: When the power fails, it will automatically connect one or more load circuits from the power supply to another to ensure the power supply of the normal load circuit. 3、Single Motor Drive: The changeover switch is driven by a single motor, stable and noiseless, with mechanical interlocking and electrical interlocking, with high changeover reliability. 4、Circuit Protection: The dual power transfer switch has short circuit, overload, undervoltage protection, with fire protection, dual output and closing signal functions to ensure safe . 5、Wide Application: Especially suitable for lighting and small motor control equipment, used for office buildings, shopping malls, banks, stations, hospitals and other lighting circuits. Specification: Item Type: Automatic Transfer Switch Model: LQ3-63 2P Material: PC Rated Voltage: 230V Coil Voltage: 220V Rated Current: 63A Frequency: 50/60Hz Specification: 2P Breaking Capacity: 35KA ATSE: Class CB Rated Current: 63A Size: Approx. 155 x 135 x 114mm / 6.1 x 5.3 x 4.5in Working Principle: The dual power controller and drive mechanism of this series use AC220V power supply, and the power signal depends on the A phase and N line of the input port of the public switch or the standby switch. When the dual power supply is in the automatic state, when the voltage of input phase A and line N of the common switch is normal (AC190-240V), the common switch will be closed preferentially regardless of whether the voltage of public power supply B, C and standby switches A, B, C and N is normal. At the same time, the power indicator and the common closed indicator light are on. When there is no voltage on the incom Package List 1 x Automatic Transfer Switch 1 x User Manual
