Why Choose the ABB 1SDA072786R1 Emax 2 E1.2N 1000 Air Circuit Breaker?
The ABB 1SDA072786R1 is a high-performance SACE Emax 2 E1.2N air circuit breaker designed for protection, switching and control in low-voltage electrical distribution systems. Configured as the E1.2N 1000 Ekip Touch LSIG 4p WMP, this four-pole withdrawable moving part combines a 1000 A rated current with ABB's advanced Ekip Touch LSIG electronic protection release.
The Ekip Touch LSIG release provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. Its adjustable electronic protection functions support coordinated system protection and selectivity, while the Ekip Touch platform provides a touchscreen interface for protection configuration and monitoring.
The E1.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA at 400/415 V AC and 50 kA at 690 V AC. Rated for operation up to 690 V AC, the four-pole withdrawable moving-part configuration is designed for connection through a corresponding Emax 2 fixed chassis part, supporting convenient inspection and maintenance.
