ABB SACE Emax 3 E1.3B 800 Protection
The 1SDA125589R1 combines the E1.3B 800 circuit-breaker platform with ABB's Ekip Aware LSI electronic release. The LSI protection configuration provides adjustable long-time and instantaneous protection, allowing the breaker to be coordinated 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 maintenance and operational procedures where the circuit-breaker moving part needs to be removed from the switchgear.
Typical Applications
- Low-voltage main distribution switchboards
- Industrial electrical distribution systems
- Commercial building power distribution
- Manufacturing and process facilities
- Motor and equipment distribution systems
- Power distribution centres
- Switchgear and electrical control assemblies
- Applications requiring withdrawable air circuit breakers
