Why Choose the ABB E2N 1600 PR121/P-LSI Air Circuit Breaker?
The ABB E2N 1600 PR121/P-LSI, order code 1SDA055897R1, is a high-performance 1600 A four-pole fixed air circuit breaker from the ABB SACE Emax family. Designed for low-voltage power distribution, it combines high-current switching capability with electronic overcurrent protection for industrial, commercial and infrastructure switchboards.
Its PR121/P-LSI R1600 electronic overcurrent release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. The LSI configuration enables coordinated protection of cables, busbars and downstream equipment while allowing short-time protection to improve selectivity within distribution networks.
The E2N 1600 has a rated uninterrupted current of 1600 A, four-pole fixed construction and horizontal rear terminals. The E2N performance class provides an ultimate short-circuit breaking capacity of 65 kA at 415 V AC and a short-time withstand current of 55 kA for 1 s, making it suitable for demanding high-current distribution applications.

Selective LSI Protection for High-Current Distribution
The ABB SACE Emax E2N platform is engineered for switching and protecting demanding low-voltage distribution circuits. Its electronic trip technology monitors current conditions and commands breaker operation when configured thresholds are exceeded, helping protect conductors, busbars and connected electrical equipment from damaging overloads and short circuits.
The PR121/P-LSI release combines long-time overload protection with short-time and instantaneous short-circuit protection. The short-time function can support improved selectivity between upstream and downstream protective devices, while the E2N's 65 kA breaking capability and 55 kA one-second withstand rating provide robust performance for high-current switchboard applications.
Typical Applications
- Industrial low-voltage switchboards.
- Main power distribution panels.
- Manufacturing and process plants.
- Commercial and infrastructure electrical distribution.
- Transformer secondary distribution systems.
- Four-wire high-current feeder and distribution circuits.
