The ABB E2S1000 PR123/P-LSIG, order code 1SDA059335R1, is a high-performance SACE Emax air circuit breaker designed for protection and switching in demanding low-voltage electrical distribution systems. Part of the proven ABB SACE Emax E2S series, this four-pole fixed circuit breaker has a rated current of 1000 A and incorporates the PR123/P-LSIG R1000 electronic overcurrent release.
The PR123/P-LSIG protection unit provides comprehensive long-time, short-time, instantaneous and earth-fault protection, helping safeguard electrical installations against overloads, short circuits and earth faults. The E2S performance level provides an ultimate short-circuit breaking capacity of 85 kA at 400–415 V AC and 65 kA at 690 V AC, supporting demanding industrial and commercial power distribution applications.
This version is a four-pole fixed circuit breaker with rear horizontal terminals. It is equipped with four auxiliary contacts and circuit-breaker open/closed position indication, supporting status monitoring and integration into industrial switchboards, distribution assemblies and control systems.
ABB SACE Emax air circuit breakers are engineered to provide dependable switching and protection for high-current low-voltage distribution circuits. The PR123/P electronic trip unit monitors electrical conditions and initiates breaker operation when configured protection thresholds are exceeded, helping protect cables, busbars and connected electrical equipment.
The LSIG protection configuration combines long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. Together with the E2S short-circuit performance level, four-pole configuration and fixed construction, the E2S1000 provides a robust solution for switchboards requiring comprehensive electronic protection and strong fault-clearing capability.
