Why Choose the ABB E1.2C 1250 Ekip Touch LI 3p WMP Air Circuit Breaker Moving Part?
The ABB E1.2C 1250 Ekip Touch LI 3p WMP, order code 1SDA072184R1, is the three-pole moving part of a withdrawable SACE Emax 2 air circuit breaker, designed for dependable protection and switching in low-voltage AC distribution systems. Rated at 1250 A, it combines ABB's compact E1.2C breaker platform with the advanced Ekip Touch electronic protection system.
The Ekip Touch LI electronic trip unit provides long-time overload (L) and instantaneous short-circuit (I) protection. Its touchscreen interface gives operators convenient access to protection settings and electrical information, while the Ekip Touch platform supports the measurement, connectivity and digital capabilities associated with ABB's Emax 2 architecture.
As a WMP moving part, the 1SDA072184R1 is designed for installation in the corresponding ABB Emax 2 withdrawable fixed part or cradle. The E1.2C performance class provides a rated ultimate short-circuit breaking capacity of 50 kA at 400 V AC, making this breaker suitable for demanding industrial, commercial and infrastructure distribution systems.

Advanced LI Protection for Withdrawable Power Distribution
The ABB Emax 2 withdrawable architecture allows the active circuit-breaker assembly to be removed from its fixed chassis, supporting efficient inspection, servicing and replacement while the permanent switchboard connections remain installed. This arrangement makes the E1.2C platform particularly suitable for distribution systems where maintainability and continuity of service are important design considerations.
The Ekip Touch LI release protects the circuit against sustained overloads and severe instantaneous short-circuit faults. Combined with the E1.2C frame's 1250 A current rating, 690 V AC rated voltage and 50 kA ultimate breaking capacity at 400 V AC, the 1SDA072184R1 provides a capable protection solution for appropriately coordinated low-voltage power networks.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process plant switchboards.
- Transformer secondary distribution systems.
- Incoming and high-current feeder protection.
- Data centres and critical electrical infrastructure.
- Withdrawable switchgear requiring convenient breaker servicing.
- Distribution circuits requiring adjustable electronic LI protection.
