1SDA100690R1 ABB Ekip Hi-Touch LSI 630 A XT5 4-Pole Trip Unit

Why Choose the ABB 1SDA100690R1 Ekip Hi-Touch LSI Trip Unit?

The ABB 1SDA100690R1 is an advanced Ekip Hi-Touch LSI electronic trip unit designed for use with compatible ABB Tmax XT5 moulded-case circuit breakers. Rated at 630 A and configured for 4-pole AC applications, it provides sophisticated 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, measurement and communication capabilities with an intuitive touchscreen interface. The LSI protection functions provide long-time overload, short-time short-circuit and instantaneous short-circuit protection, supporting precise selectivity and coordination across complex electrical distribution networks.

With a rated current of 630 A, the 1SDA100690R1 is designed to be combined with a compatible 4-pole ABB Tmax XT5 breaking unit. Its overload protection is adjustable over a 0.4–1 × In range, while short-circuit protection can be adjusted over a 1–10 × In range with time-delay functionality, providing flexibility for coordinated protection schemes.
