ABB SACE Emax 3 E1.3B 800 Protection
The 1SDA125588R1 combines the E1.3B 800 circuit-breaker platform with ABB's Ekip Aware LI electronic release. The LI protection configuration provides adjustable long-time and instantaneous protection, helping coordinate the circuit breaker with the characteristics and protection requirements of the electrical distribution system.
Its 320–800 A long-time setting range and 1200–12000 A instantaneous setting range provide flexibility when configuring protection for downstream equipment and distribution circuits. The withdrawable construction also supports switchgear arrangements where the circuit-breaker moving part needs to be removed for maintenance or operational procedures.
Typical Applications
- Low-voltage main distribution switchboards
- Industrial electrical distribution systems
- Commercial building power distribution
- Manufacturing and process facilities
- Power distribution centres
- Switchgear and electrical control assemblies
- High-current distribution feeders
- Applications requiring withdrawable air circuit breakers
