It's a 4-pole unit (neutral left) built for power distribution protection in switchgear — Category B selectivity means it coordinates with downstream breakers to isolate faults without blacking out the whole bus. Rated insulation voltage is 1000 V AC, operational voltage 440 V AC, and it carries a 12 kV impulse withstand. The 100 kA rated short-time withstand (Icw) holds for 1 second — enough for most upstream coordination windows — and the making capacity (Icm) hits 220 kA at 440 V. Drawout mounting on rails or a base plate, with front and rear connection options on both the line and load sides. Connection pitch is 115 mm. Dimensions: 556 mm wide, 439 mm high, 403 mm deep — that depth matters for enclosure sizing; the breaker needs a full 403 mm clearance behind the door for the drawout mechanism to rack out. ## Breaking performance and coordination Service breaking capacity (Ics) is 100 kA at both 220/415 V and 440 V AC — that's 100% of the ultimate capacity (Icu), meaning it can reclose and carry load after a fault at that level without derating. Maximum breaking time is 25 ms; closing response time 70 ms. Electrical durability: 10,000 cycles at In under AC-23A (motor switching), 6,000 cycles under AC-3. Mechanical durability is 15,000 cycles with periodic preventive maintenance. Standards compliance covers EN/IEC 60947-1, 60947-2, 60947-2 Annex H (for Category B selectivity), and IEC 61557-12 (for power metering if a trip unit with metering is installed).","metaTitle":"LV846192 MasterPact MTZ2 4P 1250A Drawout Circuit Breaker, 1","metaDescription":"LV846192 MasterPact MTZ2 drawout circuit breaker, 4P, 1250 A at 40 °C, H2V 100 kA at 415 V AC.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time."},{"question":"What is LV846192's listed depth (403 mm) on this component line?","answer":"The LV846192 has a listed depth of 403 mm. This is the full depth from the mounting face to the rear of the drawout cradle — critical for enclosure depth planning, especially when rack-out clearance is needed."},{"question":"What compliance documentation does this brand provide for LV846192 (RoHS, REACH, UL, IEC)?","answer":"The LV846192 is certified to EN/IEC 60947-1, EN/IEC 60947-2, EN/IEC 60947-2 Annex H, and IEC 61557-12. It is suitable for isolation per EN/IEC 60947-2. For RoHS/REACH declarations and UL listing status, request the compliance pack with your RFQ — those documents accompany the shipment."},{"question":"What is the closest pin-compatible alternative to LV846192 in this component family?","answer":"Within the MasterPact MTZ2 family, the closest alternative would be a different H2V performance variant at a lower or higher amp rating — for example, the MTZ2 08 H2V (800 A) or MTZ2 10 H2V (1000 A) share the same frame, drawout cradle, and connection pitch. The LV846192 is the 1250 A variant; stepping down means a different sensor rating and possibly a different trip unit calibration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/LV846192","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/LV846192 when reusing this data.
