ABB 1SDA070831R1 E1.2C 1250 Ekip Dip LI 3p F F

The ABB 1SDA070831R1 is a factory-identified air circuit breaker model presented as E1.2C 1250 with the Ekip Dip LI trip unit. As an air circuit breaker and ACB circuit breaker, this unit is designed to provide overcurrent and short‑circuit protection within low voltage power distribution systems. The naming on the unit indicates the exact model and protective electronics (Ekip Dip LI) used in this assembly.

This low voltage air circuit breaker is intended for installation in industrial and commercial switchgear where a three‑pole protective device is required. The ABB air circuit breaker form factor and Ekip Dip LI trip unit make it suitable for coordinated protection schemes in distribution panels and motor control centers where precise trip settings and electronic protection functions are needed. As an industrial air circuit breaker, it is selected when a dedicated, withdrawable or fixed ACB solution is needed for system protection and selective discrimination at distribution levels.
