Why Choose the ABB 1SDA072371R1 E2.2B 2000 Ekip Dip LI Air Circuit Breaker?
The ABB 1SDA072371R1 is a SACE Emax 2 E2.2B air circuit breaker designed for switching and protection in low-voltage electrical distribution systems. This three-pole withdrawable moving-part configuration has a rated uninterrupted current of 2000 A and incorporates an Ekip Dip LI solid-state electronic trip unit.
The Ekip Dip LI release provides long-time overload protection and instantaneous short-circuit protection. This LI protection profile provides essential electronic overcurrent protection for feeders, busbars and other distribution circuits without integrated short-time or earth-fault protection functions.
The E2.2B 2000 performance level provides a rated ultimate short-circuit breaking capacity of 42 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s. The breaker is supplied as the moving part of a withdrawable Emax 2 assembly and is fitted with four auxiliary contacts plus circuit-breaker open/closed position indication.

Reliable LI Protection for High-Current Power Distribution
The ABB Emax 2 E2.2B combines 2000 A current-carrying capability with electronic LI protection for low-voltage power-distribution systems. Its Ekip Dip LI release provides long-time protection against sustained overload conditions and instantaneous operation during severe short circuits, helping protect conductors, busbars, switchgear and connected electrical equipment.
With a rated ultimate short-circuit breaking capacity of 42 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s, the E2.2B platform is engineered for robust distribution duties. Its withdrawable architecture also allows the moving part to be separated from the compatible fixed part, supporting inspection, maintenance and replacement within Emax 2 switchgear.
Typical Applications
- Main low-voltage electrical distribution switchboards.
- Industrial power distribution networks.
- Manufacturing and process-industry switchgear.
- Commercial building electrical infrastructure.
- Transformer secondary distribution systems.
- Plant and machinery power distribution.
- Infrastructure and high-current distribution installations.
