Why Choose the ABB E1.2C 1250 Ekip Hi-Touch LSI 3p WMP Air Circuit Breaker?
The ABB E1.2C 1250 Ekip Hi-Touch LSI 3p WMP, order code 1SDA072188R1, is a withdrawable Emax 2 air circuit breaker (ACB) moving part designed for advanced protection, switching and isolation in low-voltage electrical distribution systems. Part of the ABB SACE Emax 2 series, this three-pole unit combines a 1250 A rated uninterrupted current with the advanced Ekip Hi-Touch LSI electronic trip unit.
The compact E1.2C platform provides high short-circuit performance for industrial and commercial switchboards while helping minimise panel space requirements. Its Ekip Hi-Touch LSI electronic release provides long-time, short-time and instantaneous protection functions, combining selective circuit protection with advanced measurement, monitoring and power-management capabilities.
With a 1250 A rated uninterrupted current, a three-pole configuration, an ultimate short-circuit breaking capacity of 50 kA at 440 V AC and a rated short-time withstand current of 42 kA for 1 s, the E1.2C 1250 is suited to demanding distribution applications. The WMP withdrawable moving-part configuration is designed for installation with the corresponding Emax 2 fixed part, supporting convenient isolation, testing and maintenance.

Advanced Selective Protection for Power Distribution
The ABB Emax 2 E1.2C combines high-performance circuit interruption with intelligent electronic protection for important low-voltage circuits. Its 1250 A current rating, 50 kA ultimate breaking capacity at 440 V AC and 42 kA short-time withstand capability for 1 s make it suitable for incoming supplies, distribution feeders and other applications where dependable fault interruption and selective coordination are required.
The Ekip Hi-Touch LSI trip unit provides long-time, short-time and instantaneous protection without the ground-fault protection function found in an LSIG configuration. Long-time protection responds to sustained overloads, short-time protection enables controlled fault clearing and improved selectivity, and instantaneous protection rapidly interrupts severe short circuits. Combined with advanced measurement and monitoring capabilities and the withdrawable Emax 2 construction, these functions provide a flexible solution for sophisticated low-voltage distribution switchboards.
Typical Applications
- Low-voltage distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Incoming and outgoing feeder protection.
- Selective and coordinated distribution networks.
- Manufacturing and production facilities.
- Infrastructure and critical power installations.
- Process and automation systems.
- High-current distribution circuits up to 1250 A.
- Switchboards requiring advanced electronic monitoring and protection.
- Withdrawable switchgear requiring convenient isolation and maintenance.
