Why Choose the ABB E1.2N 630 Ekip G Hi-Touch LSIG 4p WMP Air Circuit Breaker?
The ABB 1SDA072710R1 is an advanced SACE Emax 2 E1.2N air circuit breaker designed for protection, switching, monitoring and power management in demanding low-voltage electrical distribution systems. Rated at 630 A, this four-pole withdrawable breaker combines ABB's compact E1.2N frame with the sophisticated Ekip G Hi-Touch LSIG electronic trip unit, providing comprehensive protection against overload, short-circuit and earth-fault conditions.
As part of the ABB SACE Emax 2 platform, the E1.2N 630 provides strong short-circuit performance in a compact format. The N performance level delivers a rated ultimate short-circuit breaking capacity of 66 kA at 400 V AC, while the breaker is rated for operation at up to 690 V AC. The E1.2 platform is engineered for compact, high-performance switchboard construction in industrial, commercial and infrastructure applications.
This model is supplied as a four-pole withdrawable moving part (WMP) for connection through the appropriate separate fixed chassis. Its Ekip G Hi-Touch LSIG release combines Long-time, Short-time, Instantaneous and Ground-fault protection with advanced generator-oriented protection, measurement and monitoring functionality, making it particularly suitable for sophisticated power-distribution and generation applications.

Advanced Generator and Power-System Protection
Air circuit breakers such as the ABB SACE Emax 2 E1.2 provide a robust switching and protection point within low-voltage power systems. The Ekip G Hi-Touch LSIG release combines sophisticated electronic protection with generator-oriented functionality, measurement and monitoring capabilities, enabling the breaker to protect critical distribution and generation circuits while supporting detailed supervision of electrical operating conditions.
The E1.2N platform combines a compact frame with a 630 A current rating and 66 kA short-circuit breaking capacity at 400 V AC. Its withdrawable construction allows the moving breaker portion to be separated from the corresponding fixed chassis, supporting efficient inspection, maintenance and replacement in installations where system reliability and service continuity are important.
Typical Applications
- Generator protection and generator distribution systems.
- Main and distribution switchboards.
- Industrial low-voltage power distribution systems.
- Commercial and infrastructure electrical distribution.
- Manufacturing and process-control facilities.
- Data centres and critical-power installations.
- Emergency and standby generation systems.
- Power-management installations requiring advanced LSIG and generator protection.
