1SDA071517R1 ABB E1.2N 1600 Ekip G Touch LSIG 4-Pole Air Circuit Breaker

Why Choose the ABB 1SDA071517R1 E1.2N 1600 Ekip G Touch LSIG Air Circuit Breaker?

The ABB 1SDA071517R1 is a high-performance SACE Emax 2 E1.2N air circuit breaker designed for advanced protection and switching in low-voltage power distribution and generator applications. Rated at 1600 A, this four-pole fixed breaker combines ABB's compact E1.2N frame with the specialised Ekip G Touch LSIG electronic trip unit.

The Ekip G Touch LSIG release provides long-time overload (L), short-time overcurrent (S), instantaneous overcurrent (I) and earth-fault (G) protection together with additional functions dedicated to generator protection. ABB's Ekip G Touch platform also supports thermal memory, closing-on-short-circuit protection, external earth-fault protection, neutral protection, start-up functions and zone selectivity for S and G protection.

The 1SDA071517R1 is supplied in a fixed four-pole configuration with front terminals. Its 1600 A rating, 690 V AC capability and 66 kA breaking capacity make it suitable for demanding industrial, infrastructure and generator-connected low-voltage systems requiring sophisticated electronic protection and dependable fault interruption.

Generator-Oriented LSIG Protection for Critical Power Systems

The ABB Ekip G Touch platform extends the capabilities of the standard Ekip Touch family with protection functions specifically intended for generator applications. Alongside conventional LSI protection, the trip unit provides earth-fault protection, external earth-fault capability, thermal memory, neutral protection, start-up functionality, closing-on-short-circuit protection and zone selectivity for the S and G functions.

Combined with the 1600 A E1.2N breaker frame, Ekip Measuring Pro and a high-resolution touchscreen interface, the 1SDA071517R1 provides a sophisticated protection platform for generator-connected switchboards and critical low-voltage distribution systems where protection coordination, measurement and reliable interruption of high fault currents are essential.

Typical Applications

• Low-voltage generator protection systems.
• Generator-connected main switchboards.
• Standby and emergency power distribution.
• Industrial power generation installations.
• Critical infrastructure electrical systems.
• High-current low-voltage switchboard incomers.
• Transformer and generator distribution networks.
