1SDA072197R1 ABB E1.2N 1250 Ekip G Touch LSIG 3p WMP Air Circuit Breaker Moving Part

Why Choose the ABB E1.2N 1250 Ekip G Touch LSIG 3p WMP Air Circuit Breaker Moving Part?

The ABB E1.2N 1250 Ekip G Touch LSIG 3p WMP, order code 1SDA072197R1, is the three-pole moving part of a withdrawable SACE Emax 2 air circuit breaker, engineered for advanced generator and low-voltage power-system protection. Rated at 1250 A, it combines the compact E1.2N frame with ABB's generator-oriented Ekip G Touch electronic protection technology.

The Ekip G Touch LSIG electronic trip unit provides long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault (G) protection. The Ekip G Touch platform is specifically suited to generator applications and combines protection with measurement and monitoring functions through an intuitive touchscreen interface.

As a WMP moving part, the 1SDA072197R1 is designed for installation with the corresponding ABB Emax 2 withdrawable fixed part. The E1.2N performance level provides an ultimate short-circuit breaking capacity of 66 kA at 415 V AC and 50 kA at 690 V AC, providing robust fault interruption for demanding generator, industrial and critical-power installations.

Advanced Generator and Power-System Protection

Generator-fed electrical systems can require protection functions tailored to operating conditions that differ from conventional utility-fed networks. The ABB Ekip G Touch platform addresses these requirements by combining LSIG circuit protection with generator-oriented functions, electrical measurement and touchscreen-based configuration in a single electronic release.

Combined with the E1.2N frame's 1250 A rating, 66 kA ultimate breaking capacity at 415 V AC and 50 kA capability at 690 V AC, the 1SDA072197R1 provides a high-performance protection platform for generator incomers and critical distribution systems. Its withdrawable design also enables the breaker moving part to be removed from the fixed chassis for inspection, servicing or replacement.
