█overview

◆Introduction to switch

HLQ5 Dual Power Automatic Transfer Switch (ATSE) is an automatic transfer switch that integrates switch and logic control without the need for an external controller, truly realizing mechatronics integration. It is suitable for industrial distribution equipment with AC 50HZ, rated voltage 440V, and agreed heating current up to 3200A. It has functions such as voltage detection, communication interface, and electrical mechanical interlock, and can achieve automatic, electric remote, and forced "0" emergency manual operation. It is widely used for automatic transfer of main and backup power sources in power supply systems or automatic transfer and safety isolation of two load devices. The switch is managed by various logical commands issued by the control circuit board to control the motor. The motor drives the operating mechanism of the switch body to quickly connect and disconnect the circuit or perform circuit conversion, achieving safe isolation through obvious visible states.

◆Model and meaning

◆Switch structure description

1. Electrical key lock: controls the power supply of the internal control circuit of the control switch. When the electrical lock is turned on, the switch can achieve full automatic and strong "0". Operation: When the electrical lock is turned off, the switch can only be manually operated.

2. Operating handle: When manually operating with the operating handle, the electrical lock must be turned off first.

3. Cabinet padlock: maintenance specific, which means first use the operating handle to place the switch in the "0" position, then connect the padlock mechanism and lock it before maintenance can be carried out (connecting the padlock will cut off the internal control power supply of the switch, and the switch cannot be automatic or manually operated).

4. Indicator: Indicate the working status position of the switch (I, 0, II)

◆Main technical parameters

1. The switch complies with: IEC947-6-1 GBI4048.11-2008

2. Rated working voltage (Ue): AC400V

3. Rated connection capacity (Arms): 10 le

4. Rated breaking capacity (ARms) 8 le

5. Control power supply voltage: DC24V、48V、110V、AC220V
