Intelligent Dual Power Transfer Switch Isolation Type Power Automatic Transfer Switch 250A 4 Pole with Manual Control for Circuit Switching

Brand: Oumefar

Features:

• 【Double Row Compound Contact】Reliable mechanical interlock and electrical interlock are adopted, and independent load isolation switch is adopted for actuating components to ensure safe and reliable operation
• 【Load Isolation Switch】Zero flashover (no arcing shield) is basically realized by using double row compound contact/horizontal pull mechanism/micro-motor pre-storage and micro-electronic control technology.
• 【Saves Energy】The driver motor of the operator only passes the current at the moment when the load isolation switch is switched, which saves energy significantly.
• 【High Precision Control】Carry out load isolation switch with mechanical interlock device to gurantee that common and standby power supply work reliably without interference,
• 【Emergency Manual Operation】Four operating functions: emergency manual operation, electric remote control operation, emergency disconnection operation in automatic control state, automatic control operation

Details: Feature: Zero flashover (no arcing shield) is basically realized by using double row compound contact/horizontal pull mechanism/micro-motor pre-storage and micro-electronic control technology. Reliable mechanical interlock and electrical interlock are adopted, and independent load isolation switch is adopted for actuating components to ensure safe and reliable operation. Adopting zero-crossing technology, it can be forced to zero in emergency (cut off two power sources at the same time) to meet the needs of fire linkage; The switch of load isolation switch is driven by a single motor. The switch is reliable, stable, noiseless and has little impact force. The driver motor of the operator only passes the current at the moment when the load isolation switch is switched, which saves energy significantly. Carry out load isolation switch with mechanical interlock device to gurantee that common and standby power supply work reliably without interference. With obvious on-off position indication, padlock and other functions, reliable power and load isolation. Good safety performance, high degree of automation, high reliability, service life of more than 8000 times
