1SDA060989R1 ABB E2S-A 1200 PR121/P-LSIG 1200 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E2S-A 1200 PR121/P-LSIG 1SDA060989R1 Air Circuit Breaker?

The ABB E2S-A 1200 PR121/P-LSIG, order code 1SDA060989R1, is a high-performance SACE Emax air circuit breaker (ACB) moving part designed for protection and switching in demanding low-voltage electrical distribution systems. As part of the ABB New Emax E2 series, it combines a 1200 A rated current with comprehensive electronic protection and a withdrawable construction for industrial, commercial and infrastructure power-distribution applications.

This three-pole breaker is equipped with an ABB PR121/P-LSIG R1200 electronic overcurrent release, providing long-time, short-time, instantaneous and ground-fault protection. These LSIG functions help safeguard electrical installations against sustained overloads, short circuits and ground faults while supporting coordinated protection across low-voltage distribution networks.

With a rated current of 1200 A and a three-pole withdrawable configuration, the E2S-A 1200 is supplied as the moving part for a compatible SACE Emax draw-out circuit breaker installation. Its withdrawable construction facilitates isolation, inspection and maintenance within switchgear, making it particularly suitable for important incoming, feeder and distribution circuits where serviceability and comprehensive electronic protection are required.

Advanced Circuit Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax E2S-A provide switching and protection for high-current low-voltage distribution circuits. By combining a robust circuit-breaking mechanism with an electronic protection release, the breaker can detect abnormal electrical conditions and disconnect the affected circuit to help protect conductors, switchgear and connected equipment.

The PR121/P-LSIG R1200 trip unit provides long-time protection against sustained overloads, short-time and instantaneous protection against short-circuit conditions, and ground-fault protection for additional system protection. Combined with the withdrawable E2S-A construction, these functions provide a versatile solution for distribution systems requiring comprehensive electronic protection together with convenient circuit-breaker isolation and maintenance.

Typical Applications

• Industrial low-voltage switchboards and distribution systems.
• Main incoming circuit protection.
• High-current electrical feeder protection.
• Power distribution in manufacturing and processing facilities.
• Commercial and infrastructure electrical installations.
• Industrial plant power distribution.
• Draw-out switchgear requiring electronic LSIG protection.
