Why Choose the ABB SACE Emax 3 E1.3C 630 1SDA128977R1 Air Circuit Breaker?
The ABB 1SDA128977R1 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 E1.3C 630 four-pole withdrawable circuit breaker, it combines a 630 A rated current with an Ekip Aware LSIG electronic trip unit for comprehensive electrical protection.
This ABB SACE Emax 3 circuit breaker incorporates an Ekip Aware LSIG trip unit providing long-time, short-time, instantaneous and earth-fault protection functions. Its withdrawable construction allows the moving part to be withdrawn from the corresponding fixed installation, supporting practical inspection, maintenance and servicing of industrial switchgear.
With a rated current of 630 A and a rated ultimate short-circuit breaking capacity of 50 kA at 415 V, the E1.3C 630 is designed for low-voltage power distribution applications requiring dependable circuit protection. This product is supplied as the moving part only (WMP); the compatible fixed part is ordered separately.
