1SDA101786R1 ABB XT7L M 800 Ekip Touch Measuring LSI 800A 4-Pole MCCB

Why Choose the ABB XT7L M 800 Ekip Touch Measuring LSI 1SDA101786R1 Circuit Breaker?

The ABB 1SDA101786R1, designated XT7L M 800 Ekip Touch Meas.LSI 800 4p FF, is a high-performance four-pole moulded case circuit breaker (MCCB) designed for advanced protection, switching and electrical measurement in demanding low-voltage AC power distribution systems. Part of the ABB SACE Tmax XT7 range, it combines an 800 A rated current with an Ekip Touch Measuring LSI electronic trip unit and the very high interruption capability of the XT7L platform.

The ABB Ekip Touch Measuring LSI electronic trip unit provides long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection together with integrated electrical measurement functionality. This combination enables precise electronic circuit protection while providing useful electrical data for monitoring, energy management and advanced power-distribution applications.

With a rated current of 800 A, four-pole construction, fixed installation and front terminals, the 1SDA101786R1 is engineered for integration into industrial switchboards and high-capacity distribution assemblies. The XT7L performance level provides 120 kA short-circuit breaking performance, making this breaker particularly suitable for installations with very high prospective fault currents.
