ABB SACE Emax 3 E1.3C 800 Protection
The 1SDA125593R1 combines the E1.3C 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 electrical characteristics and protection requirements of the 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. This makes the breaker suitable for applications where dependable overcurrent protection and configurable trip thresholds are 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for use within compatible SACE Emax 3 switchgear assemblies, allowing the moving part of the air circuit breaker to be withdrawn for suitable maintenance and operational procedures. Four auxiliary contacts and open/closed position indication further support switchgear control and monitoring requirements.
