It is a Category B breaker (selectivity category per IEC 60947-2), meaning it is designed for selective coordination in a distribution system — upstream faults clear without taking downstream circuits out. The 100 kA Icw for 1 second tells you it can pass that fault current until the upstream device clears, which is the whole point of a Category B breaker in a main or tie position. ## Sizing and ratings for the BOM That is unusual at this current level; many breakers have a lower Ics. The Icm (making capacity) is 220 kA at 440 V, which governs the first half-cycle peak the breaker must close into. Power dissipation is 650 W — factor that into panel ventilation if the breaker is enclosed. Fixed mounting on rails or a base plate. Connection pitch is 115 mm. Both upside and downside connections accept front or rear terminations — choose based on your switchgear bus arrangement. The breaker is 422 mm wide, 352 mm high, 300 mm deep. IP30 enclosure protection; not rated for washdown, so keep it in a dry indoor switchgear lineup.","metaTitle":"LV846167 MasterPact MTZ2 4000 A, 100 kA Circuit Breaker","metaDescription":"LV846167 MasterPact MTZ2 fixed circuit breaker, 4000 A at 40 °C, 100 kA Icu at 440 V, 3-pole, IP30.
