Why Choose the ABB E3S 3200 PR121/P-LSIG Air Circuit Breaker?
The ABB E3S 3200 PR121/P-LSIG, order code 1SDA056306R1, is a high-performance SACE Emax air circuit breaker (ACB) designed for switching and protection of high-current low-voltage power distribution systems. Part of the ABB SACE Emax E3 series, this three-pole fixed circuit breaker combines a 3200 A rated current with the PR121/P-LSIG R3200 electronic overcurrent release for comprehensive protection in demanding industrial and commercial installations.
The PR121/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and earth-fault protection. These LSIG functions help safeguard electrical networks against overloads, delayed and instantaneous short circuits, and earth faults while supporting coordinated protection throughout low-voltage distribution systems.
The E3S 3200 features a three-pole fixed configuration with rear horizontal terminals, making it suitable for permanent integration into high-current switchboards and busbar systems. The breaker is also equipped with four change-over auxiliary contacts and open/closed position indication for integration with switchboard signalling and control systems.

Advanced LSIG Protection for Power Distribution
The PR121/P-LSIG release provides four complementary protection functions for high-current electrical networks. Long-time protection responds to sustained overloads, short-time protection permits coordinated response to short-circuit conditions, instantaneous protection provides rapid interruption of severe faults, and the earth-fault function helps detect potentially damaging current flowing through unintended earth paths.
Combining this electronic protection with the robust E3S platform makes the 1SDA056306R1 suitable for critical distribution systems where high current capacity, selective protection and dependable fault interruption are required. Its fixed construction and rear horizontal terminals provide a practical arrangement for integration into main switchboards and industrial busbar systems.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Manufacturing and process plants.
- Commercial and infrastructure electrical installations.
- Transformer-fed low-voltage distribution circuits.
- High-current switchgear and distribution assemblies.
