Why Choose the ABB 1SDA055805R1 E2B 1600 Air Circuit Breaker?
The ABB 1SDA055805R1 is a high-performance SACE Emax E2B 1600 air circuit breaker (ACB) designed for protection and switching in low-voltage power distribution systems. This four-pole fixed circuit breaker combines a 1600 A rated current with ABB's electronic PR122/P-LSIG overcurrent release, providing comprehensive protection for demanding industrial and commercial electrical installations.
As part of the ABB SACE Emax circuit breaker range, the E2B 1600 is engineered for dependable protection of distribution networks, switchboards, transformers and other high-current electrical equipment. The PR122/P-LSIG release provides long-time, short-time, instantaneous and earth-fault protection functions, allowing the breaker to respond effectively to overloads, short circuits and earth faults.
This model is supplied in a four-pole fixed configuration with horizontal rear terminals and a rated uninterrupted current of 1600 A. The E2B frame provides an ultimate short-circuit breaking capacity of 42 kA at 415 V AC and a short-time withstand current of 42 kA for 1 s, making it suitable for robust low-voltage distribution applications.

Reliable Protection for Low-Voltage Power Distribution
Air circuit breakers such as the ABB SACE Emax E2B provide switching, isolation and automatic overcurrent protection for high-current low-voltage distribution circuits. When abnormal current conditions occur, the electronic trip unit monitors the circuit and initiates breaker operation according to the configured protection characteristics.
The PR122/P-LSIG release gives this E2B 1600 comprehensive protection capability against overload, delayed and instantaneous short-circuit conditions and earth faults. Combined with the fixed four-pole construction and horizontal rear connections, the breaker is well suited to integration into industrial switchboards and power distribution assemblies.
Typical Applications
- Industrial low-voltage switchboards and distribution panels.
- Main incoming and distribution circuit protection.
- Commercial and industrial power distribution systems.
- Transformer secondary and feeder protection.
- Manufacturing plants and process facilities.
- Infrastructure and large electrical installations.
