Why Choose the ABB Ekip Dip LSI 250A XT4 3P Trip Unit?
The ABB Ekip Dip LSI In=250A XT4 3P 1SDA100273R1 is a solid-state electronic trip unit designed for three-pole ABB SACE Tmax XT4 moulded case circuit breakers. Rated at 250 A, it provides dependable electronic protection for low-voltage AC distribution systems using compatible XT4 breaking parts.
The Ekip Dip LSI release provides long-time, short-time and instantaneous protection functions. These functions protect electrical installations against overload and short-circuit conditions while providing adjustable electronic protection characteristics suitable for industrial and commercial power distribution.
Designed specifically for the ABB XT4 three-pole platform, the 1SDA100273R1 enables a compatible XT4 breaking part to be configured with a 250 A electronic protection release. Its modular construction supports flexible circuit-breaker configuration while retaining the compact dimensions and performance advantages of the Tmax XT system.

Electronic LSI Protection for ABB XT4 Circuit Breakers
The ABB Ekip Dip LSI release monitors current through the circuit breaker and provides electronic protection according to its configured protection thresholds. Long-time protection responds to sustained overloads, short-time protection provides controlled response to short-circuit currents, and instantaneous protection acts rapidly when severe fault currents occur.
As a modular trip unit, the 1SDA100273R1 is intended for use with a compatible ABB XT4 breaking part rather than as a standalone circuit breaker. This modular approach allows the breaking performance and protection release to be selected according to the requirements of the electrical distribution system.
