Principle

ABB SACE EMAX E1N 16 adopts electronic protection principle. The ABB SACE EMAX E1N 16 current sensors collect three-phase current signals and send them to the electronic trip unit. The trip unit calculates and compares measured current with preset thresholds, and triggers the trip mechanism when overload, short-circuit or earth fault occurs. The main contact opens to cut off the fault circuit. The matched YO and YC coils realize remote electrical opening and closing. The electronic adjustable protection structure of the ABB SACE Emax E1N air circuit breaker provides accurate and flexible power system protection.

Applications

This ABB SACE EMAX E1N 16 is widely used in industrial main switch rooms, commercial building power distribution systems, data center power panels, marine low-voltage distribution and generator sets. It is applied for incoming switch, bus tie and important feeder protection. It is used for spare replacement and retrofit of legacy ABB Emax low voltage switchgear. The ABB SACE EMAX E1N 16 delivers dependable power distribution protection and control for low voltage electrical systems as a proven E1N 1600A air circuit breaker.
