ABB SACE Emax 3 E1.3N 630 Protection
The 1SDA125583R1 combines the E1.3N 630 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 electrical characteristics and protection requirements of the distribution system.
Its 252–630 A long-time setting range and 945–9450 A instantaneous setting range provide flexibility when configuring protection for downstream equipment and distribution circuits. The E1.3N performance class provides 66 kA Icu at 440 V and 50 kA Icw for 1 s, supporting applications where high fault-current withstand capability is required.
The withdrawable WMP configuration is designed for use within compatible SACE Emax 3 switchgear assemblies, allowing the moving part of the air circuit breaker to be withdrawn for suitable maintenance and operational procedures.
