The Iu (160 A) is the maximum continuous current the breaker body and terminals can carry; the In (40 A) is the installed protection setting. This means the same breaker shell can be re-trip'd up to 160 A by swapping the electronic trip unit — useful if the load grows and you want to avoid pulling the whole breaker. The Ekip LSIG trip provides L (long-time), S (short-time), I (instantaneous), and G (ground-fault) protection curves. The G function is the differentiator here — it detects leakage currents down to the trip unit's adjustable threshold, which matters for personnel protection on IT or TN-S systems where a standard LI or LSI breaker would miss a ground fault until it became a phase fault. ## 4-pole switching — when you need to break the neutral Four poles means all three phases plus the neutral are switched and protected. This is mandatory in TN-S or TT distribution where the neutral is a current-carrying conductor that must be isolated for safe maintenance. It also simplifies coordination in dual-source transfer schemes where the neutral path must be broken to prevent circulating currents. Rated 690 V, so it covers 400 V and 480 V systems with headroom for voltage swells, and it's suitable for 690 V industrial grids common in mining, marine, and heavy process plants. The 50/60 Hz rating means it's at home on either side of the pond. ## Sourcing and lifecycle — still a catalog item Estimated lead time is 2-4 weeks, which is typical for a built-to-order MCCB. Not a stocked shelf item, but the lead time is standard for the class and predictable for project planning.","metaTitle":"ABB 1SDA068158R1 XT4N 160 Ekip LSIG, 40 A, 4-Pole MCCB","metaDescription":"ABB 1SDA068158R1 XT4N 160 molded-case circuit breaker, 40 A In, 160 A Iu frame, Ekip LSIG trip unit, 4-pole, 690 V, 50/60 Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["MCCB up to 100A"],"specifications":{"In":"40","Iu":"160","Size":"XT4","Type":"XT4N 160 Ekip LSIG In=40A 4p F F","title":"1SDA068158R1","Weight":"3.1 Kg","Trip units":"Ekip LSIG","Product No.":"1SDA068158R1","description":"Distribution Circuit Breakers","Product Type":"Distribution Circuit Breakers","Number of Poles":"4 poles","Shipping Weight":"5 Kg","lifecycle_stage":"current","Dimensions (LxWxH)":"8.25cm x 14cm x 16cm","Rated Current (In)":"40 A","Rated Voltage (Ur)":"690 V","Estimated Lead Time":"2 - 4 weeks.","Rated Frequency (f)":"50 / 60 Hz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,101.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/8fb355278a49072eefa66def9c6257d7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does the Ekip LSIG trip unit protect against?","answer":"Ekip LSIG provides L (long-time overload), S (short-time fault), I (instantaneous fault), and G (ground-fault) protection.
