Why Choose the ABB 1SDA072774R1 Emax 2 E1.2C 1000 Air Circuit Breaker?
The ABB 1SDA072774R1 is a SACE Emax 2 E1.2C air circuit breaker designed for protection, switching and control in low-voltage electrical distribution systems. Configured as the E1.2C 1000 Ekip Touch LI 4p WMP, this four-pole withdrawable moving part combines a 1000 A rated current with ABB's advanced Ekip Touch LI electronic protection release.
The Ekip Touch LI release provides long-time overload and instantaneous short-circuit protection. This protection combination provides electronic overcurrent protection while the Ekip Touch platform offers a sophisticated interface for protection configuration, measurement and monitoring within modern electrical distribution systems.
The E1.2C performance level combines the compact E1.2 frame with 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, supporting convenient inspection and maintenance in compatible switchboard assemblies.

Advanced LI Protection for Low-Voltage Distribution
The ABB SACE Emax 2 E1.2C provides switching and overcurrent protection for low-voltage electrical distribution systems. Its electronic trip unit monitors circuit current and initiates interruption when configured protection thresholds are exceeded, helping protect conductors, switchgear and connected equipment against overload and high-current short-circuit conditions.
The Ekip Touch LI release combines long-time overload protection with instantaneous short-circuit protection in an advanced electronic trip-unit platform. Together with the 1000 A E1.2C frame, 50 kA short-circuit breaking performance and withdrawable architecture, the ABB 1SDA072774R1 provides a capable solution for distribution switchboards requiring electronic protection and service-friendly circuit-breaker construction.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial electrical distribution systems.
- Transformer and feeder protection.
- Manufacturing and process facilities.
- Commercial and institutional building power distribution.
- Infrastructure electrical installations.
