1SDA071575R1 ABB E2.2H 1000 Ekip Touch LSI 4p FHR Air Circuit Breaker

Why Choose the ABB E2.2H 1000 Ekip Touch LSI 4p FHR Air Circuit Breaker?

The ABB E2.2H 1000 Ekip Touch LSI 4p FHR, order code 1SDA071575R1, is a high-performance four-pole air circuit breaker (ACB) from the ABB SACE Emax 2 range, designed for protection, control and switching in demanding low-voltage power distribution systems. Its E2.2H performance level combines very high short-circuit interruption capability with the advanced Ekip Touch LSI electronic trip unit.

Rated at 1000 A, this breaker is supplied in a fixed configuration with rear horizontal terminals. The Ekip Touch LSI solid-state release provides long-time overload, short-time selective short-circuit and instantaneous short-circuit protection, while its touch-sensitive display supports convenient protection configuration, electrical measurements and operating supervision.

The E2.2H performance level provides an ultimate short-circuit breaking capacity of 100 kA at 380–440 V AC and 85 kA at 500–690 V AC. With a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC and operation at 50/60 Hz, the 1SDA071575R1 is well suited to industrial switchboards, infrastructure and critical distribution systems with high prospective fault currents.

Advanced LSI Protection with Ekip Touch

The Ekip Touch LSI electronic trip unit provides three complementary protection stages for low-voltage distribution systems. Long-time protection responds to sustained overloads, short-time protection enables selective coordination during short-circuit conditions, and instantaneous protection rapidly disconnects severe faults before they can cause excessive damage to downstream equipment.

The Ekip Touch interface provides convenient access to protection settings and electrical operating information, while the E2.2H breaker frame delivers the high interruption capability required for networks with substantial prospective fault currents. This combination makes the 1SDA071575R1 particularly suitable for main distribution and critical industrial switchboards where protection selectivity and high breaking performance are important.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Manufacturing and process facilities.
• Commercial buildings and infrastructure.
• Data centres and critical power installations.
• Transformer secondary distribution circuits.
• Power control centres and automated switchboards.
• Networks with high prospective short-circuit currents.
