Split Double Power Automatic Transfer Switch YES1-125N
1) Rated current?:40,63,80,100 125A 2) Pole number: 2p, 3p, 4p
3) Rated working voltage: AC 240V/415V, 50/60Hz General Automatic switch and its corresponding intellectual displayer ,which are mainly used in such sites as high-rise building, post & communication, coal mines, vessels, military establishments,industrial streamlines which need the uninterrupted power. Under the inevitable trend of dramatic increasing demand for municipal power, they can more satisfy the higher requirements for the power utilization reliability.
They are designed in a whole compact body, and the electrical-mechanical interlocking ensures that the main backup power supplies cannot be closed simultaneously. The position of both power supplies is in switch-off state designed with the isolation function. The disjunction current is the instant exciting mode. ? Standard
