Why Choose the ABB 1SDA060925R1 E1N-A 800 Air Circuit Breaker?
The ABB 1SDA060925R1, manufacturer designation E1N-A 800 PR121/P-LSIG In=800A 3p W, is a SACE Emax E1N-A withdrawable air circuit breaker designed for protection and switching in low-voltage power distribution systems. This three-pole breaker combines an 800 A rated current with ABB's PR121/P-LSIG electronic trip unit.
The PR121/P electronic trip unit provides comprehensive LSIG protection functions, incorporating long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. This combination provides protection against common overcurrent and earth-fault conditions in industrial, commercial and infrastructure electrical distribution systems.
The 1SDA060925R1 combines the E1 frame with ABB's N-A performance class and a three-pole withdrawable construction. Its withdrawable execution allows the breaker moving portion to be inserted into or removed from a compatible SACE Emax fixed part, supporting inspection, servicing and replacement in switchboards where maintainability and operational flexibility are important.
