1SDA072368R1 ABB E2.2H 1600 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker 1600 A

Why Choose the ABB E2.2H 1600 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker?

The ABB E2.2H 1600 Ekip Hi-Touch LSI 3p WMP, order code 1SDA072368R1, is a high-performance 1600 A three-pole withdrawable air circuit breaker from the ABB SACE Emax 2 range. It combines the high-breaking-capacity E2.2H frame with ABB's advanced Ekip Hi-Touch LSI solid-state electronic trip unit for sophisticated protection, measurement and monitoring in demanding low-voltage AC distribution systems.

The Ekip Hi-Touch LSI release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. This LSI configuration is particularly suited to installations requiring adjustable overcurrent protection and selective coordination without an integrated G earth-fault protection function, while the Hi-Touch platform adds advanced electrical measurement and power-management capabilities.

Rated at 1600 A and 690 V AC, the E2.2H performance level provides a rated ultimate short-circuit breaking capacity of 100 kA at 400 V AC and retains 85 kA breaking capability at the higher-voltage end of the E2.2H range. Its withdrawable moving-part construction facilitates inspection, maintenance and replacement in critical industrial and commercial switchboards.

Advanced LSI Protection for High-Fault-Level Distribution Systems

The ABB SACE Emax 2 E2.2H is engineered for electrical distribution systems where high prospective short-circuit currents require substantial interruption capability. With a rated ultimate short-circuit breaking capacity of 100 kA at 400 V AC, the E2.2H frame is well suited to main incomers, transformer-fed switchboards and critical distribution networks where robust fault protection is essential.

The Ekip Hi-Touch LSI release combines adjustable long-time, short-time delayed and instantaneous protection with the advanced measurement and monitoring capabilities of ABB's Hi-Touch platform. The short-time function supports selective coordination between upstream and downstream protective devices, while instantaneous protection enables rapid interruption of severe short-circuit faults. This combination makes the 1SDA072368R1 suitable for sophisticated installations where protection performance, selectivity and electrical system visibility are key requirements.
