Why Choose the ABB 1SDA059307R1 E2S1000 Air Circuit Breaker?

The ABB 1SDA059307R1 is a high-performance SACE Emax E2S1000 air circuit breaker (ACB) designed for protection and switching in low-voltage electrical distribution systems. As part of the ABB New Emax series, this four-pole fixed circuit breaker combines a 1000 A rated current with the PR121/P electronic trip unit for reliable overload and short-circuit protection.

Configured with LSI protection, the PR121/P trip unit provides long-time, short-time and instantaneous protection functions. This combination makes the breaker suitable for industrial switchboards, transformer and generator protection, power distribution systems and infrastructure installations where dependable fault interruption and selective protection are required.

The E2S1000 has a rated uninterrupted current of 1000 A and a rated operational voltage of up to 690 V AC. This configuration features four poles, fixed mounting and rear horizontal terminals, while the E2S performance level provides an ultimate short-circuit breaking capacity of 85 kA at 415 V AC and 65 kA at 690 V AC.

Reliable Protection for High-Demand Power Distribution

Air circuit breakers such as the ABB SACE Emax E2S1000 protect low-voltage electrical installations against overloads and short circuits while providing dependable switching and isolation. The high short-circuit performance of the E2S version makes it particularly suitable for industrial distribution systems where substantial prospective fault currents may occur.

The PR121/P electronic trip unit provides LSI protection through long-time overload, short-time short-circuit and instantaneous short-circuit functions. Combined with the four-pole fixed Emax platform, this provides effective protection coordination for demanding low-voltage distribution networks while allowing the neutral conductor to be switched as part of the four-pole arrangement.

Typical Applications

  • Main low-voltage electrical distribution boards.
  • Industrial switchboards and switchgear assemblies.
  • Transformer and generator protection systems.
  • Manufacturing and process plant electrical systems.
  • Commercial and infrastructure power distribution.
  • Four-pole distribution systems requiring neutral switching.
  • High-fault-level industrial electrical networks.
