1SDA100905R1 ABB XT7H 1600 Ekip Touch LSI 1600A 3-Pole Circuit Breaker

Why Choose the ABB 1SDA100905R1 XT7H 1600 Circuit Breaker?

The ABB 1SDA100905R1, type XT7H 1600 Ekip Touch LSI In=1600A 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 1600 A rated current with the advanced Ekip Touch LSI electronic trip unit for dependable overload, short-time and instantaneous short-circuit protection.

The Ekip Touch LSI solid-state electronic release provides long-time, short-time and instantaneous protection functions with adjustable settings for effective system coordination. Long-time protection can be set from 0.4–1 × In, short-time protection from 0.6–10 × In and instantaneous protection from 1.5–10 × In, providing flexibility for demanding high-current distribution networks.

The XT7H performance level delivers an ultimate short-circuit breaking capacity of 70 kA at 415 V AC and maintains substantial interruption 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 systems, main distribution panels and high-current feeder circuits.
