ABB 1SDA074172R1

The ABB Ekip Supply 110-240VAC/DC (Part Number: 1SDA074172R1) is a dedicated auxiliary power supply module designed for ABB's Emax 2 air circuit breakers and Tmax XT molded case circuit breakers. As a critical accessory, this module provides a stable 110-240V AC/DC power source to the Ekip trip units and additional communication modules, ensuring reliable operation even when the main circuit is de-energized. The Ekip Supply module is mounted in the circuit breaker's terminal box and serves as the power backbone for all Ekip series protection and control devices. Its wide-range input capability makes it equally suitable for conventional AC auxiliary supplies and DC-busbar-fed installations, reducing the need for separate AC and DC variants in a single project.
