Why Choose the ABB E4S-A 3200 PR121/P-LSIG Air Circuit Breaker?
The ABB E4S-A 3200 PR121/P-LSIG, order code 1SDA057823R1, is a high-performance SACE Emax air circuit breaker designed for protection and switching in demanding low-voltage electrical distribution systems. As part of the ABB SACE Emax E4 series, this three-pole fixed circuit breaker combines a 3200 A rated current with the advanced PR121/P-LSIG electronic overcurrent release.
The PR121/P-LSIG trip unit provides comprehensive long-time, short-time, instantaneous and ground-fault protection, helping protect electrical installations against overloads, short circuits and earth faults. The E4S-A platform is engineered for high-current applications where dependable circuit protection, robust switching performance and integration into low-voltage switchboards are required.
With a 3200 A rated current, three-pole fixed construction and rear horizontal terminals, the 1SDA057823R1 is suited to high-capacity industrial and commercial power distribution. At 480 V, the E4S-A 3200 frame provides a 65 kA short-circuit current rating, while the breaker incorporates an R3200 rating plug, four auxiliary contacts and open/closed position indication.

Advanced Circuit Protection for High-Current Power Distribution
Air circuit breakers such as the ABB SACE Emax E4S-A provide switching and overcurrent protection for high-capacity low-voltage distribution circuits. They are commonly installed in main switchboards and industrial distribution assemblies where reliable interruption of overload and short-circuit currents is essential for protecting electrical equipment and maintaining system availability.
The PR121/P-LSIG electronic release combines four key protection functions within the circuit breaker. Long-time protection responds to sustained overload conditions, short-time and instantaneous functions provide short-circuit protection, and ground-fault protection helps detect potentially damaging current flowing to earth. Together with the E4S-A frame's high-current capability, these functions make the 1SDA057823R1 suitable for demanding electrical distribution installations.
Typical Applications
- Main low-voltage electrical switchboards.
- High-current industrial power distribution systems.
- Manufacturing and process facilities.
- Commercial building electrical infrastructure.
- Power generation and utility distribution equipment.
- Motor control centres and plant distribution systems.
- High-capacity feeders requiring electronic LSIG protection.
