1SDA072734R1 ABB E1.2C 800 Ekip Touch LI 4P WMP Air Circuit Breaker

Why Choose the ABB E1.2C 800 Ekip Touch LI 4p WMP Air Circuit Breaker?

The ABB 1SDA072734R1 is a compact, high-performance SACE Emax 2 E1.2C air circuit breaker designed for protection and switching in low-voltage electrical distribution systems. Rated at 800 A, this four-pole withdrawable breaker combines ABB's E1.2C frame with an advanced Ekip Touch LI electronic trip unit, providing Long-time overload and Instantaneous short-circuit protection.

As part of the ABB SACE Emax 2 range, the E1.2C 800 combines compact switchboard integration with strong electrical performance. The C performance level provides a rated ultimate short-circuit breaking capacity of 50 kA at 400 V AC, while the breaker has a rated voltage of 690 V AC, making it suitable for demanding industrial, commercial and infrastructure power-distribution systems.

This model is supplied as a four-pole withdrawable moving part (WMP) for connection through the appropriate separate Emax 2 chassis or fixed part. Its Ekip Touch LI release combines electronic circuit protection with ABB's touchscreen-based Ekip interface, while four auxiliary change-over contacts and open/closed breaker position indication support integration into modern switchboards and control systems.

Reliable Electronic Protection for Power Distribution

Air circuit breakers such as the ABB SACE Emax 2 E1.2 provide a robust switching and protection point within low-voltage electrical systems. The Ekip Touch LI release provides Long-time protection against sustained overload conditions and Instantaneous protection against severe short-circuit faults, helping protect conductors and downstream equipment from damaging overcurrents.

The E1.2C platform combines a compact Emax 2 frame with an 800 A current rating and 50 kA ultimate 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 inspection, servicing and replacement in installations where maintainability and continuity are important.

Typical Applications

• Main and distribution switchboards.
• Industrial low-voltage power distribution systems.
• Commercial building electrical distribution.
• Manufacturing and process-control facilities.
• Infrastructure and utility installations.
• Transformer secondary distribution.
• Generator and auxiliary power distribution systems.
• Four-pole circuits requiring electronic overload and instantaneous short-circuit protection.
