Why Choose the ABB E1N 1600 PR123/P-LSIG Air Circuit Breaker?
The ABB E1N 1600 PR123/P-LSIG, order code 1SDA055791R1, is a high-performance 1600 A four-pole withdrawable air circuit breaker designed for switching and protection in low-voltage power distribution systems. As part of the ABB SACE Emax series, it combines robust high-current switching capability with the advanced PR123/P-LSIG electronic overcurrent release for demanding industrial, commercial and infrastructure installations.
The PR123/P-LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. The PR123/P platform offers advanced protection and measurement capabilities, supporting accurate monitoring, protection coordination and dependable operation in sophisticated low-voltage distribution networks.
With a rated current of 1600 A and a four-pole withdrawable configuration, the E1N 1600 is particularly suitable for switchboards where comprehensive protection, maintainability and operational flexibility are required. Its withdrawable construction enables the circuit breaker to be isolated from the compatible fixed part for inspection and servicing, while the four-pole arrangement supports applications requiring switching and protection of four conductors.
