-W-N3 for the three-stage automatic transfer switch, the switch after receiving the converted signal can be immediately (or after a predetermined delay time) from a transducer connected to another power supply, you can pick from a power exchange to any intermediate position does not disconnect the power interlinked. 20A current specifications for a 5000A.
-Reliable mechanical interlock: a unique eccentric selection structure, to ensure that only one set of power supply, there could not be two sets of power while the access load.
-Excellent arc performance: a variety of abnormalities will be reliably extinguish the arc, arc duration is short, less contact loss.
-Multi-piece main arc contacts: contact surface contact area and increase the contact pressure, without overheating or contact welding, to extend the service life of the contacts.
-Switching speed fast: in between two common power supply and backup power conversion quickly with
