1SDA071685R1 ABB E2.2H 2000 Ekip Touch LSI 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2.2H 2000 Ekip Touch LSI 4p FHR Air Circuit Breaker?

The ABB E2.2H 2000 Ekip Touch LSI 4p FHR, order code 1SDA071685R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for switching and selective protection in demanding low-voltage power distribution systems. This fixed four-pole E2.2H configuration combines a 2000 A rated current with ABB's Ekip Touch LSI electronic trip unit and rear horizontal main terminals.

The Ekip Touch LSI release provides long-time overload (L), short-time short-circuit (S) and instantaneous short-circuit (I) protection. The inclusion of short-time protection allows coordinated fault-clearing strategies to be implemented between upstream and downstream devices, while the Ekip Touch interface provides convenient electronic configuration and access to breaker operating information.

The E2.2H performance level is designed for installations with high prospective fault currents, providing an ultimate short-circuit breaking capacity of 100 kA at 380–440 V AC and 85 kA at 500–690 V AC. Combined with its 2000 A current rating and fixed four-pole construction, the 1SDA071685R1 is well suited to main switchboards, transformer secondary systems, industrial incomers and other critical high-current distribution circuits.

High-Performance Selective Protection for 2000 A Distribution

The ABB SACE Emax 2 E2.2H is engineered for critical switching and protection duties where high prospective short-circuit currents must be safely interrupted. Its 2000 A current capability and breaking performance reaching 100 kA make this configuration particularly suitable for main distribution points close to transformers, generators and other high-capacity power sources.

The Ekip Touch LSI release combines three complementary protection functions. Long-time protection responds to sustained overloads, short-time protection allows delayed and selective clearance of short-circuit conditions, and instantaneous protection rapidly disconnects severe faults. This combination enables robust circuit protection while supporting coordination with downstream breakers in carefully engineered distribution systems.

Typical Applications

• Main low-voltage switchboards and power-distribution assemblies.
• Industrial main incomer protection.
• Transformer secondary distribution systems.
• High-current feeder circuits.
• Manufacturing and process facilities.
• Data centres and critical power infrastructure.
• Large commercial and infrastructure electrical systems.
• High-fault-level networks requiring selective overload and short-circuit protection.
