ABB 1SDA074172R1 EKIP SUPPLY 110-240VAC/DC E1.2..E6.2-XT Power Supply Module

The ABB 1SDA074172R1 EKIP SUPPLY 110-240VAC/DC E1.2..E6.2-XT is a dedicated power supply module designed for the ABB Emax 2 series air circuit breakers, providing a wide-range 110–240 V AC/DC auxiliary supply to the EKIP protection and control unit. This module ensures reliable operation of the EKIP electronic trip unit across the full E1.2 through E6.2-XT breaker frame range, making it an essential accessory for installations where independent auxiliary power is required.

Applications & Use Cases

The EKIP SUPPLY 110-240VAC/DC E1.2..E6.2-XT module is specified wherever an ABB Emax 2 air circuit breaker must operate from an external auxiliary supply rather than relying solely on the main circuit current. Typical applications include main incomer breakers in low-voltage switchgear panels, generator protection assemblies, data centre power distribution boards, and industrial automation control systems where the EKIP trip unit must remain energised independent of load current. Its wide-range AC/DC input makes it equally suitable for DC-busbar-fed installations and conventional AC auxiliary supplies, reducing the need for separate AC and DC variants in a single project.
