Bypass Isolation Switches

In both Hospitals and Data Centers, the continuity of electrical service is of vital importance. Upon failure of the Normal electrical supply, the Essential Electrical System is required, capable of supplying a limited amount of essential electrical energy in critical facilities, whose task avoids putting both human life and health at risk, in hospitals, as well as the information of companies and institutions that serve millions of users in data centers.

In accordance with Article 517.31 of NOM-001-SEDE-2018, the Essential Electrical System must consist of three independent transfer switches.
