ABB 1SDA071582R1 E2.2N 1250 Ekip Dip LSI 4p F HR

The ABB 1SDA071582R1 is an air circuit breaker configured as a 4p, 1250 A unit with an Ekip Dip LSI trip assembly as shown in the product title. This ACB circuit breaker is a modular, withdrawable-style device intended for use within low-voltage switchgear assemblies where centralized protection and selective coordination are required. As an ABB air circuit breaker, it integrates the documented trip unit type and frame/current rating in a single catalog item.

This low voltage air circuit breaker is typically specified where a clear, catalogued protection device is required for feeders and distribution buses in commercial and industrial installations. The presence of the Ekip Dip LSI trip unit denotes the breaker’s intended role in offering combined long-time, short-time, and instantaneous protection functions as part of a coordinated protection scheme. Engineers and electricians use this industrial air circuit breaker when replacing or specifying like-for-like breakers in existing switchgear or when designing new low-voltage distribution panels that call out the same trip unit and current rating.
