1SDA100899R1 ABB XT7H 1000 Ekip Dip LSIG 1000A 3-Pole Circuit Breaker

Why Choose the ABB 1SDA100899R1 XT7H 1000 Circuit Breaker?

The ABB 1SDA100899R1, type XT7H 1000 Ekip Dip LSIG In=1000A 3p F F, is a high-performance moulded case circuit breaker (MCCB) for low-voltage power distribution. Part of the ABB SACE Tmax XT range, this XT7H breaker combines a 1000 A rated current with an Ekip Dip LSIG solid-state electronic trip unit for comprehensive overload, short-time, instantaneous short-circuit and earth-fault protection.

The Ekip Dip LSIG electronic release provides L, S, I and G protection functions, enabling coordinated protection against sustained overloads, short-circuit faults and earth faults. Its long-time overload setting is adjustable from 400–1000 A, while the instantaneous short-circuit protection range extends from 1500–15000 A, providing flexibility for demanding distribution applications.

The XT7H performance level is designed for installations with high prospective fault currents, providing an ultimate short-circuit breaking capacity of 70 kA at 415 V AC and 65 kA at 440 V AC. Its fixed three-pole construction, front terminals and lever operating mechanism provide a robust configuration for industrial switchboards, main distribution panels and high-current electrical assemblies.

Comprehensive Electronic Protection for Power Distribution Systems

The ABB Ekip Dip LSIG electronic trip unit combines long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection in a single solid-state release. The L, S, I and G functions support selective protection coordination throughout complex low-voltage networks while providing dedicated protection against faults between live conductors and earth.

The XT7H version is engineered for installations where substantial short-circuit interruption capability is required. With its 1000 A rating, 70 kA ultimate breaking capacity at 415 V AC and fixed front-terminal configuration, the 1SDA100899R1 is particularly suited to industrial switchboards, main distribution panels, infrastructure installations and high-current feeder circuits requiring comprehensive electronic protection.

Typical Applications

• Industrial low-voltage distribution switchboards.
• Main and sub-main electrical distribution.
• High-fault-level power distribution systems.
• Circuits requiring integrated earth-fault protection.
• Commercial and industrial electrical installations.
