Why Choose the ABB 1SDA072725R1 Emax 2 E1.2B 800 Air Circuit Breaker?
The ABB 1SDA072725R1 is a SACE Emax 2 E1.2B air circuit breaker designed for protection, switching and control in low-voltage electrical distribution systems. Configured as the E1.2B 800 Ekip Touch LSI 4p WMP, this four-pole withdrawable moving part combines a rated uninterrupted current of 800 A with ABB's advanced Ekip Touch LSI electronic protection release.
The Ekip Touch LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. Its adjustable electronic protection functions support coordination and selectivity within distribution networks, while the Ekip Touch platform provides an intuitive interface for configuring and monitoring protection parameters.
The E1.2B performance level provides an ultimate short-circuit breaking capacity of 42 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s. The withdrawable moving-part design connects to a separate fixed chassis, supporting convenient inspection, servicing and replacement within compatible Emax 2 switchboards.

Advanced Protection for Low-Voltage Power Distribution
The ABB SACE Emax 2 E1.2B provides switching and overcurrent protection for low-voltage electrical distribution systems. Its electronic trip unit continuously evaluates circuit current and can initiate interruption when configured protection thresholds are exceeded, helping protect conductors, switchgear and connected equipment against overload and short-circuit conditions.
The Ekip Touch LSI release combines long-time overload, short-time short-circuit and instantaneous short-circuit protection. Together with the E1.2B frame's 42 kA short-circuit performance and withdrawable construction, the ABB 1SDA072725R1 provides a flexible solution for distribution switchboards requiring electronic protection, selectivity and convenient maintenance.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial electrical distribution systems.
- Manufacturing and process facilities.
- Commercial building power distribution.
- Infrastructure electrical installations.
- Distribution systems requiring selective short-circuit protection.
