Why Choose the ABB E2S1000 PR121/P-LSIG 1000A 3-Pole Withdrawable Air Circuit Breaker?
The ABB E2S1000 PR121/P-LSIG, order code 1SDA059310R1, is a high-performance 1000 A three-pole withdrawable air circuit breaker moving part designed for switching and protecting demanding low-voltage power distribution systems. As part of the proven ABB SACE Emax E2S series, it combines robust high-current switching capability with electronic overcurrent and earth-fault protection for industrial, commercial and infrastructure switchgear.
This Emax circuit breaker is equipped with the PR121/P-LSIG R1000 electronic trip unit, providing long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection. This comprehensive LSIG protection package helps safeguard cables, busbars, transformers, switchgear and connected equipment while supporting coordinated protection throughout the electrical distribution system.
With a rated current of 1000 A, the E2S1000 provides a higher short-circuit performance level than the E2N frame and is suited to installations with demanding prospective fault currents. This model is supplied as the three-pole moving part of a withdrawable circuit breaker and is fitted with four auxiliary contacts plus circuit-breaker open/closed position indication for integration into compatible SACE Emax switchgear.

Reliable Circuit Protection for Power Distribution
Air circuit breakers such as the ABB SACE Emax E2S are designed to switch and protect high-current low-voltage distribution circuits. The electronic trip unit monitors circuit conditions and initiates breaker operation when configured protection thresholds are exceeded, helping safeguard cables, busbars, transformers, switchgear and connected equipment against damaging overload, short-circuit and earth-fault conditions.
The PR121/P-LSIG release provides a comprehensive combination of long-time, short-time, instantaneous and earth-fault protection. Combined with the E2S performance level and withdrawable construction, the E2S1000 is particularly well suited to critical distribution systems where strong fault protection, selective coordination and straightforward switchgear maintenance are important.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process plant switchgear.
- Transformer and feeder protection.
- Systems requiring earth-fault protection.
- Infrastructure and utility installations.
- Protection of busbars and high-current distribution circuits.
