1SDA101170R1 ABB XT7H 800 Ekip Dip LS/I 800 A 4-Pole MCCB

Why Choose the ABB 1SDA101170R1 XT7H 800 Circuit Breaker?

The ABB 1SDA101170R1 is a high-performance four-pole moulded-case circuit breaker (MCCB) designed for protection and switching in demanding low-voltage power distribution systems. Part of the ABB SACE Tmax XT7 range, this fixed circuit breaker combines an 800 A rated current with an Ekip Dip LS/I electronic trip unit for reliable electronic circuit protection.

The integrated Ekip Dip LS/I electronic trip unit provides long-time overload, selective short-time and instantaneous short-circuit protection. The LS/I configuration allows the short-time and instantaneous protection functions to be selected as required, providing a practical protection solution for feeders, distribution circuits and other high-current electrical installations.

The XT7H performance level provides a rated ultimate short-circuit breaking capacity of 70 kA at 415 V AC. The 1SDA101170R1 features a fixed four-pole construction with front terminals, making it suitable for switchboards and three-phase distribution systems requiring four-pole switching and dependable high-fault-level protection.
