Why Choose the ABB 1SDA057215R1 E1B-A 800 Air Circuit Breaker?
The ABB 1SDA057215R1 is a SACE Emax E1B-A air circuit breaker designed for protection and switching in low-voltage power distribution systems. Identified as E1B-A 800 PR121/P-LSIG In=800A 3p F, this three-pole fixed breaker combines an 800 A rated current with the ABB PR121/P-LSIG electronic overcurrent release.
As part of the ABB SACE Emax E1 platform, the breaker is designed for industrial, commercial and infrastructure installations requiring reliable overload, short-circuit and ground-fault protection. Its fixed construction provides permanent installation within compatible low-voltage switchgear and distribution assemblies.
The integrated PR121/P-LSIG electronic trip unit provides long-time, short-time, instantaneous and ground-fault protection functions. This LSIG configuration gives the 1SDA057215R1 comprehensive protection against common overcurrent and earth-fault conditions in three-phase electrical distribution systems.

Comprehensive LSIG Protection for Low-Voltage Power Distribution
Air circuit breakers such as the ABB SACE Emax E1B-A are used to switch and protect low-voltage distribution circuits carrying substantial electrical loads. When abnormal current conditions occur, the electronic release initiates circuit interruption according to its configured protection settings, helping safeguard switchgear, conductors, transformers and connected electrical equipment.
The PR121/P-LSIG release provides four principal protection functions. Long-time protection responds to sustained overloads, short-time protection supports controlled short-circuit response and selective coordination, instantaneous protection provides rapid interruption during severe faults, and ground-fault protection detects potentially damaging current flowing to earth.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Manufacturing and process facilities.
- Commercial building electrical distribution.
- Infrastructure power systems.
- Transformer secondary distribution.
- Generator and installation protection systems.
- Switchgear requiring an 800 A three-pole fixed air circuit breaker with LSIG electronic protection.
