Eaton Cutler-Hammer I.B. 48020 is a mechanical latch attachment for Type SL Medium Voltage Vacuum Contactor. It allows the contactor to maintain the closed position when power is removed from the main operating coil. A separate unlatch coil must then be energized to allow the contactor to open. The unlatch coil is intermittently rated and should only be energized for a short duration to allow the contactor to open. The latch (closing) coil is continuously rated, but power should be removed after the contactor is closed to ensure that it opens when the unlatch coil is energized.
