1SDA061041R1 ABB E2S-A 800 PR123/P-LSIG 800 A 3-Pole Withdrawable Air Circuit Breaker

Why Choose the ABB E2S-A 800 PR123/P-LSIG 1SDA061041R1 Air Circuit Breaker?

The ABB 1SDA061041R1 is an E2S-A 800 A three-pole withdrawable air circuit breaker moving part from the ABB SACE Emax range, designed for dependable protection and switching in demanding low-voltage power 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 electrical installations.

As part of the ABB New Emax product family, the E2S-A combines robust circuit-breaking technology with sophisticated electronic protection and a withdrawable construction that supports efficient switchboard inspection, servicing and replacement. The PR123/P trip unit provides advanced protection functionality, while the moving-part configuration is designed for use with a compatible Emax withdrawable fixed part.

With a rated current of 800 A and a three-pole withdrawable configuration, the 1SDA061041R1 is suitable for high-current three-phase distribution systems. This configuration incorporates an R800 overcurrent release, an Im 12000 A instantaneous setting reference, four auxiliary contacts and open/closed position indication for integration into industrial switchboards and power distribution assemblies.

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 dependable protection, system coordination and continuity of service are important.

The PR123/P-LSIG electronic release provides long-time protection against sustained overloads, short-time protection to support selective coordination, instantaneous protection against severe short circuits and earth-fault protection. Combined with the withdrawable Emax construction, these functions provide a flexible and serviceable solution for sophisticated low-voltage 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.
• Withdrawable switchboard installations requiring 800 A three-pole circuit protection.
