1SDA071669R1 ABB E2.2N 2000 Ekip Hi-Touch LSIG 4-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2.2N 2000 Ekip Hi-Touch LSIG 4p FHR Air Circuit Breaker?

The ABB E2.2N 2000 Ekip Hi-Touch LSIG 4p FHR, order code 1SDA071669R1, is a high-performance SACE Emax 2 air circuit breaker (ACB) designed for advanced protection and switching in demanding low-voltage power distribution systems. This fixed four-pole E2.2N configuration combines a 2000 A rated current with ABB's Ekip Hi-Touch LSIG solid-state electronic trip unit and rear flat horizontal main terminals.

The Ekip Hi-Touch LSIG release provides long-time overload (L), short-time selective short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. This comprehensive protection package makes the breaker particularly suitable for critical distribution networks where overload protection, selective fault clearance and earth-fault protection must be combined within a single advanced electronic release.

The E2.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA at 400–690 V AC, while its rated short-time withstand capability is 66 kA for 1 s and 50 kA for 3 s. Rated for operation up to 690 V AC, the 1SDA071669R1 provides a robust solution for main switchboards, transformer secondary systems, industrial incomers and critical high-current distribution networks.

Advanced Selective and Ground-Fault Protection

The ABB SACE Emax 2 E2.2N is engineered for switching and protection at critical points within high-current low-voltage networks. Its 2000 A current capability, consistent 66 kA ultimate breaking capacity and substantial short-time withstand performance make this configuration suitable for main distribution circuits where fault interruption, selectivity and continuity of service are important design considerations.

The Ekip Hi-Touch LSIG release combines four complementary protection functions. Long-time protection responds to sustained overloads, short-time protection supports selective coordination, instantaneous protection rapidly interrupts severe short circuits, and ground-fault protection detects earth-fault conditions. Together, these functions provide a comprehensive electronic protection solution for sophisticated low-voltage distribution systems.

Typical Applications

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