1SDA101173R1 ABB XT7H 1600 Ekip Dip LS/I In=1600A 4p F F Circuit Breaker

Why Choose the ABB XT7H 1600 Ekip Dip LS/I In=1600A 4p F F Circuit Breaker?

The ABB XT7H 1600 Ekip Dip LS/I In=1600A 4p F F, order code 1SDA101173R1, is a high-performance four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax XT range. Designed for demanding low-voltage power distribution applications, it combines a 1600 A rated current with an Ekip Dip LS/I solid-state electronic trip unit and the high-breaking-capacity XT7H performance level.

The Ekip Dip LS/I electronic release provides adjustable long-time overload and instantaneous short-circuit protection. Its long-time protection can be set from 0.4–1 × In, while instantaneous protection is adjustable from 1–10 × In, allowing the protective response to be coordinated with the characteristics of the electrical installation.

As an XT7H version, the 1SDA101173R1 provides a rated ultimate short-circuit breaking capacity of 70 kA at 415 V AC. Its four-pole fixed construction, front terminals and lever operating mechanism make it particularly suitable for high-current industrial and commercial switchboards where substantial fault-interruption capability is required.

High-Capacity Electronic Protection for Power Distribution

The ABB Ekip Dip LS/I trip unit combines adjustable long-time overload protection with instantaneous short-circuit protection. On this 1600 A model, the overload threshold can be adjusted across 640–1600 A, while instantaneous protection spans 1600–16000 A, allowing the circuit breaker's response to be matched to the protection requirements of the installation.

The XT7H platform is designed for electrical systems requiring increased short-circuit interruption capability. With 70 kA Icu and Ics at 415 V AC, a 20 kA short-time withstand rating and a 690 V AC rated operational voltage, the 1SDA101173R1 provides robust protection for high-current feeders, main distribution boards and demanding industrial power systems.
