ABB 1SDA071822R1 E4.2N 4000 Ekip Dip LSI 4p F HR

This ABB 1SDA071822R1 air circuit breaker is presented as a factory-identified ACB intended for use in low-voltage distribution equipment. The product title identifies the unit as part of the E4.2N line and references an Ekip Dip LSI trip arrangement in a four-pole configuration, indicating the breaker is designed for selective protection and coordination within electrical distribution panels. As an industrial air circuit breaker, it is a component sized for switching and protection duties in commercial and industrial installations.

In low-voltage power distribution, this ACB circuit breaker is used where robust switching and adjustable protection are required — for example, at incoming switchgear, distribution buses, or large feeder circuits. ACB circuit breakers such as this are chosen in switchgear layouts for their ability to provide reliable fault interruption, configurable trip characteristics, and straightforward integration with control and metering accessories. The listing identifies this specifically as an ABB air circuit breaker, which is commonly specified where replaceable trip units and accessible maintenance are priorities.
