    Function

    Mains changeover switches are manually operated changeover switches with overlapping contacts (make before break) which allow a 1-pole, 2-pole (1-pole + N), 3-pole and 4-pole (3-pole + N) changeover. They enable electrical supply or load changeover for maintenance purposes.

    Function

    With bypass switches the energy flow can be changed over from UPS supply to direct mains supply without interruption and with the UPS input either connected or disconnected. Bypass switches can be configured as 1-pole, 2-pole (1-pole + N), 3-pole and 4-pole (3-pole + N) version. UPS bypass switches offer make before break contacts ensuring that whilst switching any interruption of the power supply is impossible.
