Why Choose the ABB E2N 1600 PR121/P-LSIG Air Circuit Breaker?
The ABB E2N 1600 PR121/P-LSIG, order code 1SDA055898R1, 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 robust high-current switching with comprehensive electronic protection for industrial, commercial and infrastructure switchboards.
Its PR121/P-LSIG R1600 electronic overcurrent release provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. This LSIG configuration helps safeguard cables, busbars and connected equipment while supporting selective coordination across demanding electrical distribution networks.
With a rated current of 1600 A and a four-pole fixed configuration, the E2N 1600 is designed for permanent installation in compatible low-voltage switchboards. Its four-pole construction is particularly suitable for four-wire distribution systems where switching and comprehensive protection of the distribution circuit are required.

Comprehensive LSIG 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 initiates breaker operation when configured protection thresholds are exceeded, helping protect conductors, busbars and connected electrical equipment against damaging overloads, short circuits and earth faults.
The PR121/P-LSIG release combines four key protection functions within a single electronic trip unit. Long-time, short-time and instantaneous protection address different overcurrent conditions, while the earth-fault function adds protection against ground-fault currents, making the 1SDA055898R1 a comprehensive solution for important four-pole distribution circuits.
Typical Applications
- Industrial low-voltage switchboards.
- Main power distribution panels.
- Manufacturing and process plants.
