1SDA059324R1 ABB E2S1000 PR122/P-LSIG 1000A 4-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E2S1000 PR122/P-LSIG 1000A 4-Pole Withdrawable Air Circuit Breaker?

The ABB E2S1000 PR122/P-LSIG, order code 1SDA059324R1, is a high-performance 1000 A four-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 comprehensive electronic overcurrent and earth-fault protection for industrial, commercial and infrastructure switchgear.

This Emax circuit breaker is equipped with the PR122/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. Its adjustable protection functions support selective coordination while helping safeguard cables, busbars, transformers, switchgear and connected equipment against overload, short-circuit and earth-fault conditions.

With a rated uninterrupted current of 1000 A, rated voltage of 690 V AC and an ultimate short-circuit breaking capacity of 85 kA at 400 V AC, the E2S1000 is suited to demanding distribution systems with high prospective fault currents. This model is supplied as the four-pole moving part of a withdrawable circuit breaker and includes four auxiliary contacts with 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 PR122/P-LSIG release provides long-time, short-time, instantaneous and earth-fault protection with adjustable settings for coordinated distribution protection. Combined with the E2S high short-circuit performance level and four-pole withdrawable construction, the E2S1000 is well suited to critical installations where strong fault interruption capability, neutral switching and service-friendly breaker removal are required.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Commercial building electrical distribution.
• Manufacturing and process plant switchgear.
• Three-phase four-wire distribution systems.
• Transformer and feeder protection.
• Systems requiring integrated earth-fault protection.
• Infrastructure and utility installations.
• Protection of busbars and high-current distribution circuits.
