CB Class Automatic Transfer Switch

LVMA Dual Power Automatic Transfer Switch ATS Changeover Transfer Switching CB Class Solar System Electric Device

Plastic case circuit breaker dual power supply is a dual power switching device composed of two plastic case circuit breakers and their accessories, mechanical interlocking transmission mechanism, intelligent controller, etc

This series of Automatic transfer switch is suitable for AC 50Hz/60Hz,rated working voltage 230V/400V and below power distribution and control circuit.The current up to 63A.It is mainly used as the main switch of terminal electrical appliances,and can also be used to control various types of motors,low-power electrical appliances, lighting and other places. Comply with GB/T14048.11 and IEC947-6-1 standards.

① Auto/Manual mode control switch: When the control switch at theright position, it’s in automatic mode, and when the control switch atthe left position, it’s in manual mode.

② Mian power indicator: When the main power voltage is normal, thisindicator on. It turns off when main power phase is missing, flashesrapidly at 10Hz when main power overvoltage, and flashes slowly at2Hz when main power undervoltage.

③ Emergency power indicator: When the emergency power voltage isnormal, this indicator on. Turn off when emergency powerabnormal.

④Emergency on indicator: When the emergency circuit breaker isclosed, this indicator on. Flashes slowly at 2Hz when theemergency circuit breaker trips.

⑤ Mian on indicator: When the main circuit breaker is closed, thisindicator on. Flashes slowly at 2Hz when the main circuit breaker trips.

⑥ Terminal 1,2 and 3 is start generator output terminal: When themain power supply is normal, port 3 and 2 will turn off. And port and 2 will turn on. And port 3 and 1 will turn off. It is recommended to connect normally closed contacts port 3 and port 2.

⑦ Terminal 4-5: Main power on state passive output port.

⑧ Terminal 6-7: Emergency power on state passive output port.

⑨ Terminal 8-9: RS485 communication port.

⑩ Terminal 10-11 Fire input: When DC9~48V is input, the switch turnsto OFF position. If you need to release the fire state, you canmanually pull the Manual/Auto switch, and turn the switch in
