Why Choose the ABB 1SDA072818R1 Emax 2 E1.2C 1250 Air Circuit Breaker?
The ABB 1SDA072818R1 is a SACE Emax 2 E1.2C air circuit breaker designed for advanced protection, switching and power management in low-voltage electrical distribution systems. Configured as the E1.2C 1250 Ekip Hi-Touch LSI 4p WMP, this four-pole withdrawable moving part combines a 1250 A rated current with ABB's advanced Ekip Hi-Touch LSI electronic protection release.
The Ekip Hi-Touch LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. Its advanced electronic platform supports precise protection configuration, measurement and system monitoring, while the LSI protection combination is particularly useful where selective coordination between upstream and downstream protective devices is required.
The E1.2C performance level provides an ultimate short-circuit breaking capacity of 50 kA and a rated short-time withstand current of 42 kA. Its four-pole withdrawable moving-part construction is designed for use with the corresponding Emax 2 fixed part, providing a service-friendly solution for demanding industrial, commercial and infrastructure switchboards.
