1SDA100691R1 ABB Ekip Hi-Touch LSIG 250 A XT5 4-Pole Trip Unit

Why Choose the ABB 1SDA100691R1 Ekip Hi-Touch LSIG Trip Unit?

The ABB 1SDA100691R1 is an advanced Ekip Hi-Touch LSIG electronic trip unit designed for use with compatible ABB Tmax XT5 moulded-case circuit breakers. Rated at 250 A and configured for 4-pole AC applications, it provides comprehensive electronic protection for demanding low-voltage power distribution systems.

As part of the ABB SACE Tmax XT range, the Ekip Hi-Touch platform combines advanced protection with measurement, communication and digital functionality. The LSIG protection functions provide long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection, supporting precise selectivity and coordination throughout complex electrical distribution networks.

With a rated current of 250 A, the 1SDA100691R1 is designed to be combined with a compatible 4-pole ABB Tmax XT5 breaking unit. Its electronic protection is adjustable for overload over a 0.4–1 × In range and short-circuit protection over a 1–10 × In range, with time-delay capability supporting coordinated protection schemes.
