Why Choose the ABB SACE Emax 3 E1.3N 800 1SDA128981R1 Air Circuit Breaker?
The ABB 1SDA128981R1 is a reliable SACE Emax 3 air circuit breaker moving part designed for protection and control of low-voltage electrical distribution systems. Configured as an E1.3N 800 four-pole withdrawable circuit breaker, it provides an 800 A rated current together with an Ekip Aware LSIG electronic trip unit for comprehensive circuit protection.
The integrated Ekip Aware LSIG trip unit provides long-time, short-time, instantaneous and earth-fault protection functions for low-voltage distribution applications. Its withdrawable construction enables the moving part to be withdrawn from the corresponding fixed installation, supporting practical inspection, servicing and maintenance of switchgear.
With a rated current of 800 A and a rated ultimate short-circuit breaking capacity of 66 kA at 415 V, the E1.3N 800 is designed for demanding low-voltage power distribution applications. This product is supplied as the moving part only (WMP); the compatible fixed part is ordered separately.
