That Ics figure equals the ultimate capacity (Icu) on this unit — meaning after clearing a 66 kA fault, the breaker is ready to be reclosed without derating. The H1 performance variant delivers 66 kA Ics across the full voltage range up to 690 V AC. Rated insulation voltage (Ui) is 1000 V AC, operational voltage (Ue) 690 V AC, and impulse withstand (Uimp) 12 kV — figures that place this breaker squarely in heavy industrial distribution, not light commercial. The 145 kA making capacity (Icm) at 415 V AC handles the inrush when closing onto a bolted fault, and the 66 kA short-time withstand (Icw) for 1 second allows delayed tripping for full selectivity coordination. ## Selectivity and coordination — Category B Category B (IEC 60947-2) is the key distinction here: this breaker is designed for selective coordination, not just individual protection. The 66 kA Icw for 1 s means downstream devices can clear a fault while the MTZ2 holds closed, avoiding a total plant blackout. For a site electrical engineer building a discrimination study, that 1-second withstand window is the parameter that governs upstream breaker sizing and cable thermal stress limits. The electrical durability is rated at 10,000 cycles at 440 V and 690 V AC under EN/IEC 60947-2, with 6,000 cycles in AC-3 motor-switching duty. Mechanical durability hits 25,000 cycles with periodic preventive maintenance — a realistic figure for a main breaker that sees infrequent switching but must be reliable when called upon. ## Lifecycle and sourcing status Compliance documentation covers EN/IEC 60947-1, EN/IEC 60947-2, EN/IEC 60947-2 Annex H, and IEC 61557-12. Storage range is -40 to 85 °C. ## Physical integration — fixed mount, 4P Fixed-mount format on rails or base plate. Dimensions: 537 mm wide, 352 mm high, 300 mm deep. Connection pitch is 115 mm. Both front and rear connections are available on the upside and downside, giving panel builders flexibility in busbar routing and cable entry. The neutral position is on the right (standard for 4P configurations). Push-button control type, without an integral control unit — so external trip/alarm accessories or a separate control unit (e.g., Micrologic trip unit) would be specified separately for this frame. IP30 protection rating suits indoor switchgear assemblies; for dusty or damp environments, enclosure-level protection is required.","metaTitle":"Schneider LV848186 MasterPact MTZ2 1600A 4P Circuit Breaker,","metaDescription":"Schneider LV848186 MasterPact MTZ2 4P fixed circuit breaker, 1600 A rated at 40°C, 66 kA Ics at 415 V AC.
