Automatic transfer switches
Automatic transfer switches
Device application for changing supplies
- Rated current: 63~3200A
- Poles description: 2P, 3P, 4P
- Switching sequence: A <-> B or A <-> OFF <-> B
Features
- Excellence and Characteristics: Excellent swithching performance and unfailing operation function. Most suitable for emergency power facility which is neutral position
- Safety: Safety and steady operation applying BMC mold at the breaking component. Strong protection based on latch structure.
- Single coil with transient exciting method: Power saving structure because of transient exciting method which secures reliable power. Solenoid operation.
- Unfailing insullation characteristics: Molded breaking component which is completed sealed prevent electric shock. Prevent electric accidents from alien substance.
