Why Choose the ABB SACE Emax 3 E2.3S 1250 1SDA128998R1 Air Circuit Breaker?

The ABB SACE Emax 3 E2.3S 1250 1SDA128998R1 is a high-performance air circuit breaker designed for reliable protection and control of low-voltage electrical distribution systems. As part of the ABB SACE Emax 3 circuit breaker series, this 4-pole breaker combines a 1250 A rated current with an Ekip Aware LSIG trip unit for comprehensive protection in demanding power distribution applications.

This breaker is supplied in a withdrawable moving-part-only configuration (WMP), allowing it to be used with the appropriate separately ordered fixed part within a compatible Emax 3 installation. The Ekip Aware LSIG trip unit provides long-time, short-time, instantaneous and ground-fault protection functions for flexible circuit protection.

With a rated current of 1250 A and an Icu of 85 kA at 415 V, the E2.3S 1250 is suitable for high-capacity electrical distribution systems where dependable fault protection and operational flexibility are required.

Reliable Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB SACE Emax 3 E2.3S 1250 provide switching and protection for high-current low-voltage electrical distribution systems. Their electronic trip units continuously monitor electrical conditions and initiate protective operation when configured fault conditions occur.

The Ekip Aware LSIG trip unit provides four principal protection functions: long-time protection for overload conditions, short-time protection, instantaneous protection for high-level faults and ground-fault protection. This combination allows the breaker to be configured for demanding power distribution applications.

Typical Applications

  • Low-voltage main distribution systems.
  • Industrial electrical distribution switchboards.
  • Commercial and infrastructure power distribution.
  • High-current feeder protection.
  • Industrial power control and distribution assemblies.
  • Withdrawable switchgear and electrical distribution systems.
