ABB SACE XT4H 250 EKIP LSI 3P Circuit Breaker

ABB SACE Tmax XT4H 250 EKIP LSI 3P Circuit Breaker is a fixed, three‑pole molded‑case protective device with front terminals and an EKIP LSI electronic trip unit. Rated In at 250 A, it provides precise overload and short‑circuit protection for three‑phase feeders in ABB SACE Tmax XT4 family switchgear. This UL/CSA‑listed configuration is designed for compliant installation in commercial and light industrial distribution panels, with a lever‑operated mechanism for reliable manual operation. The EKIP LSI trip unit delivers adjustable protection parameters and local sensing to coordinate protection with downstream devices, while the front‑terminal, three‑pole design simplifies installation and maintenance in compact spaces. In regional variants, the XT4H 250 offers substantial short‑circuit capability (an example specification cited is up to 70 kA at 380 V), making it suitable for feeders and service entrances that require robust, certified protection. This model embodies the XT4H lineage’s focus on compact form, precise protection, and easy integration within ABB’s Tmax XT ecosystem, providing dependable, standards‑based protection for three‑phase circuits up to 250 A with a modern electronic trip unit.
