static transfer switch / upright

Installing a Master Switch static transfer switch provides additional resilience and protection from the disruption that can be caused by the failure of a single power
source. The result is the absolute protection of industrial utilities and critical information technology against power supply and load faults.

OPERATING PRINCIPLE
Master Switch guarantees a source of redundant power, allowing the load to be switched between to alternative and independent power sources. Switching can be automatic (when a supply source falls outside of acceptable tolerances) or manually done by an operator from the front panel or remotely.

PROTECTION AGAINST POWER SUPPLY FAULTS
If one of the two power sources falls outside tolerance levels, Master Switch will transfer the consumers to the second power source (switching is instantaneous if the two sources are in phase).

PROTECTION AGAINST ENVIRONMENTAL DISTURBANCES
In the event of an overload, the user can decide the level of intervention of the
internal protection devices in order to block the power supply. In the extreme case of a downstream short circuit, Master Switch disconnects the load in order to avoid
jeopardising the operation of the other loads (i.e. in the event of poor selectivity of
the protection devices).
