ABB 1SDA070822R1 E1.2B 1250 Ekip Dip LSI 3p F F

The ABB 1SDA070822R1 is an industrial air circuit breaker configured as a 3‑pole unit with a 1250 A rated current and an Ekip Dip LSI trip unit. This exact ACB circuit breaker provides overcurrent, short‑circuit and adjustable protection delivered through the Ekip Dip LSI electronics, making it a defined protective element in low voltage switchgear and distribution panels. As an ABB air circuit breaker, it is supplied as a factory‑configured assembly whose markings and model code identify the precise trip unit and frame ratings.

In low voltage power distribution, this low voltage air circuit breaker is installed at main distribution boards, incoming feeder bays, and critical motor or busbar protection positions where a 1250 A rated device is required. The combination of a 3‑pole configuration and the Ekip Dip LSI trip unit makes this ACB circuit breaker appropriate where coordinated long‑time and short‑time protection plus instantaneous and earth‑fault functions are needed. Engineers and panel builders select this ABB air circuit breaker for its clear specification (frame, poles, and trip) and for integration into withdrawable or fixed switchgear assemblies that require a defined protection set.

The ACB circuit breaker format is chosen in switchgear when a single, compact device must provide primary protection, selective coordination, and simple replacement or maintenance. As an industrial air circuit breaker, this model is intended where thermal‑magnetic and electronic trip characteristics (as provided by the Ekip Dip LSI) are required to protect distribution feeders, transformer feeders or groups of motors while allowing adjustable protection settings to match site coordination studies.

• Brand: ABB
• SKU / Catalog Number: 1SDA070822R1
• Product Series: E1.2B

Application areas for this ABB air circuit breaker include main and feeder protection in commercial and industrial distribution boards, protection of transformer secondary circuits sized around 1250 A, and feeder protection for groups of motors where adjustable long‑time, short‑time and instantaneous protection (via the Ekip Dip LSI) is required. This configuration is suited to electrical installers, panel builders and facility engineers specifying a clearly defined ACB circuit breaker for coordinated low voltage protection schemes.
