1SDA061039R1 ABB E2S-A 800 PR123/P-LSIG 800 A 3-Pole Fixed Air Circuit Breaker

Why Choose the ABB E2S-A 800 PR123/P-LSIG 1SDA061039R1 Air Circuit Breaker?

The ABB 1SDA061039R1 is a high-performance E2S-A 800 A three-pole fixed air circuit breaker from the ABB SACE Emax range, designed for reliable protection and switching in demanding low-voltage electrical distribution systems. Equipped with the advanced PR123/P-LSIG electronic overcurrent release, it provides long-time, short-time, instantaneous and earth-fault protection for industrial and commercial power distribution applications.

As part of the ABB New Emax product family, the E2S-A combines robust circuit-breaking performance with sophisticated electronic protection. This configuration uses an R800 rating plug, fixed execution and horizontal rear terminals, making it suitable for integration into low-voltage switchboards where dependable protection and effective system coordination are required.

With a rated current of 800 A, a three-pole configuration and an Im 12000 A instantaneous setting reference, the E2S-A 800 provides a capable protection solution for three-phase power distribution. The breaker is supplied with four auxiliary contacts and open/closed position indication for integration with switchboard monitoring and control systems.

Advanced Protection for Low-Voltage Power Distribution

Air circuit breakers such as the ABB E2S-A protect low-voltage electrical networks against overloads, short circuits and earth faults while providing switching and isolation within the distribution system. They are particularly suited to main switchboards and high-current distribution assemblies where reliable protection, system selectivity and continuity of service are important.

The PR123/P-LSIG electronic release provides long-time protection against sustained overloads, short-time protection for selective coordination, instantaneous protection against severe short circuits and earth-fault protection. Combined with the E2S-A breaker platform, these functions provide comprehensive protection for sophisticated industrial and commercial power distribution systems.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Commercial building electrical distribution.
• Manufacturing and process plant switchgear.
• Power distribution and control assemblies.
• Fixed switchboard installations requiring 800 A three-pole circuit protection.
