Abstract: An electromagnet for an automatic transfer switch and a corresponding automatic transfer switch. The electromagnet includes a static iron core, a coil, a magnetic yoke and a movable iron core. The static iron core is fixedly disposed on a base and at an end of the electromagnet. The coil has an annular shape and is disposed adjacent to the static iron core. The magnetic yoke is disposed between the coil and the static iron core and defines an inner space together with the static iron core and the coil. The movable iron core is partially disposed within the inner space and configured to move between a first position and a second position relative to the static iron core along a center axis of the electromagnet.

Abstract: An interlock device for a bypass device, which includes a Rack In Rack Out (RIRO) mechanism, configured to drive an Automatic Transfer Switching Equipment (ATSE) from a non-operating position to an operating position and drive the ATSE from the operating position to the non-operating position. Further, the interlock device includes a first interlock mechanism which is configured to prevent the RIRO mechanism from driving the ATSE from the non-operating position to the operating position when the first switch and the fourth switch are both switched on. The interlock device also includes a second interlock mechanism which is configured to prevent the RIRO mechanism from driving the ATSE from the non-operating position to the operating position when the second switch and the third switch are both switched on.

Abstract: An interlock device for a bypass device. The bypass device is configured to switch a load between a main power supply and an auxiliary power supply and includes an Automatic Transfer Switching Equipment having a first switch coupled to the main power supply and a second switch coupled to the auxiliary power supply. The bypass device also includes a Manual Transfer Switching Equipment having a third switch coupled to the main power supply and a fourth switch coupled to the auxiliary power supply. The interlock device includes a mounting plate having a first side and a second side opposite to the first side; a first support member arranged at the first side of the mounting plate; and a first interlock assembly configured to prevent the first switch from being closed when the fourth switch is closed.
