1SDA100897R1 ABB XT7H 1600 Ekip Dip LSI 1600A 3-Pole Circuit Breaker

Why Choose the ABB 1SDA100897R1 XT7H 1600 Circuit Breaker?

The ABB 1SDA100897R1, type XT7H 1600 Ekip Dip LSI In=1600A 3p F F, is a high-performance moulded case circuit breaker (MCCB) for transformer, generator and electrical installation protection. Part of the ABB SACE Tmax XT range, this XT7H breaker combines a 1600 A rated uninterrupted current with an Ekip Dip LSI solid-state electronic trip unit for dependable protection of demanding low-voltage power distribution systems.

The Ekip Dip LSI electronic release provides long-time, short-time and instantaneous protection functions. This combination protects against sustained overloads and short-circuit faults while supporting selective coordination between upstream and downstream protective devices, helping maintain continuity across complex industrial and commercial distribution networks.

The XT7H performance level delivers an ultimate short-circuit breaking capacity of 70 kA at 415 V AC and maintains substantial breaking capability across operating voltages up to 690 V AC. Its fixed three-pole construction, front terminals and lever operating mechanism provide a robust configuration for industrial switchboards, transformer and generator protection, main distribution panels and high-current feeder circuits.

Selective Electronic Protection for High-Current Power Systems

The ABB Ekip Dip LSI electronic trip unit combines long-time overload, short-time short-circuit and instantaneous short-circuit protection in a solid-state release. Short-time protection enables improved selectivity between protective devices, allowing engineers to coordinate fault-clearing characteristics throughout complex low-voltage networks while retaining rapid instantaneous protection against severe faults.

The XT7H version is engineered for installations where substantial fault interruption capability is required. With its 1600 A rating, 70 kA ultimate breaking capacity at 415 V AC, 20 kA short-time withstand current and fixed front-terminal configuration, the 1SDA100897R1 is particularly suited to industrial switchboards, transformer and generator systems, main distribution panels and high-current feeder circuits.
