Why Choose the ABB E1.2N 1000 Ekip G Touch LSIG 4p F F Air Circuit Breaker?

The ABB E1.2N 1000 Ekip G Touch LSIG 4p F F, order code 1SDA071437R1, is an advanced four-pole air circuit breaker (ACB) designed for generator and low-voltage power distribution protection. Part of the ABB SACE Emax 2 series, this fixed circuit breaker combines a 1000 A rated current, high short-circuit performance and the generator-specific Ekip G Touch LSIG electronic protection release.

The integrated Ekip G Touch LSIG electronic trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection together with dedicated generator protection functions. Integrated Ekip Measuring Pro capabilities provide electrical measurement functionality, while the touch-sensitive display enables convenient configuration and supervision of the protection system.

With a rated operational voltage of 690 V AC, rated insulation voltage of 1000 V AC and an ultimate short-circuit breaking capacity of 66 kA at 400/415 V AC, the E1.2N 1000 provides robust protection in the compact Emax 2 E1.2 frame. This version features a four-pole fixed configuration with front terminals, making it suitable for generator installations and sophisticated three-phase four-wire power distribution assemblies.
