Why Choose the ABB E2S 800 PR121/P-LSIG Air Circuit Breaker?
The ABB E2S 800 PR121/P-LSIG, order code 1SDA058308R1, is a SACE Emax air circuit breaker moving part designed for protection and switching in demanding low-voltage power-distribution systems. This model combines an 800 A rated current, four-pole configuration and PR121/P-LSIG R800 electronic overcurrent release in a withdrawable moving-part execution.
The withdrawable configuration allows the breaker moving part to be used with the appropriate compatible SACE Emax fixed part, supporting switchboard designs where isolation, inspection and servicing are important considerations. Its four-pole arrangement enables switching of the three phases and neutral, making it suitable for a wide range of three-phase distribution systems.
The PR121/P-LSIG release provides long-time, short-time, instantaneous and ground-fault protection. Combined with the E2S frame's high short-circuit performance and short-time withstand capability, this comprehensive protection package makes the 1SDA058308R1 particularly suitable for important incoming and feeder circuits where coordinated overcurrent and earth-fault protection are required.
Key Advantages
- 800 A rated current for substantial low-voltage distribution circuits.
- Four-pole construction provides switching of three phases and neutral.
- PR121/P-LSIG R800 electronic release provides comprehensive overcurrent and ground-fault protection.
- Long-time, short-time, instantaneous and ground-fault functions support coordinated system protection.
- Withdrawable moving-part execution supports serviceable and maintainable switchboard designs.
- 85 kA breaking capacity at 415 V AC suits installations with substantial prospective fault currents.
- 65 kA short-time withstand current for 1 s supports selective protection strategies.
- ABB SACE Emax construction provides purpose-designed integration with compatible E2 fixed parts and accessories.

Reliable LSIG Protection with Withdrawable Switchboard Integration
The PR121/P-LSIG electronic release combines four complementary protection functions. Long-time protection responds to sustained overloads, short-time protection provides delayed short-circuit protection for improved coordination, instantaneous protection rapidly clears severe short circuits, and ground-fault protection detects qualifying current flowing outside the normal phase-current paths.
Combined with the E2S breaker's 85 kA breaking capability at 415 V AC and 65 kA short-time withstand capability for 1 s, the 1SDA058308R1 provides a strong platform for selective low-voltage distribution protection. Its withdrawable construction is particularly useful in switchboards where the breaker must be isolated from the main power connections using a compatible fixed part for servicing and maintenance procedures.
Typical Applications
- Withdrawable low-voltage main distribution switchboards.
- Industrial incoming and feeder circuits.
- Manufacturing and process facilities.
- Commercial building power distribution.
- Infrastructure and utility distribution systems.
- Transformer secondary protection.
- Four-pole systems requiring neutral switching.
- Installations requiring LSIG overcurrent and ground-fault protection.
