Why Choose the ABB 1SDA069640R1 XT4L 250 Ekip E-LSIG 250A 4-Pole Circuit Breaker?
The ABB 1SDA069640R1, designated XT4L 250 Ekip E-LSIG In=250A 4p F F, is a fixed four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range. Built on the XT4L 250 frame and rated at 250 A, it is designed for protection and switching in demanding low-voltage power distribution systems.
The integrated Ekip E-LSIG electronic trip unit provides comprehensive LSIG protection, covering long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault conditions. Electronic protection enables accurate fault detection and adjustable protection characteristics for effective coordination within industrial and commercial distribution networks.
This model has a four-pole configuration and is supplied for fixed installation with front terminals. The XT4L performance level is intended for applications requiring high short-circuit interruption capability, while the Ekip E-LSIG release has a short-circuit setting range extending from 1–10 × In.

Advanced LSIG Protection for High-Performance Distribution
The Ekip E-LSIG electronic release combines four essential protection functions within the circuit breaker. Long-time protection responds to sustained overloads, short-time and instantaneous functions protect against short-circuit faults, and ground-fault protection detects damaging current paths to earth. Together, these functions provide comprehensive protection for cables, switchgear and connected electrical equipment.
The XT4L performance class is designed for distribution systems with elevated prospective fault currents. Combined with the 250 A rating, four-pole architecture and configurable electronic protection, the 1SDA069640R1 provides a compact solution for demanding industrial and commercial low-voltage switchboards.
Typical Applications
- Industrial low-voltage distribution switchboards.
