The LV848194 is a MasterPact MTZ3 fixed-mount circuit breaker rated 4000 A at 40 °C, 4 poles, with an H1 performance class delivering 100 kA Icu/Ics across the full voltage range up to 690 V AC. That 100 kA Ics at 440 V means it clears a fault and can be immediately reclosed without inspection — a key spec for selective coordination in industrial distribution where you need Category B selectivity (the breaker itself is rated Category B per IEC 60947-2). The Icw of 100 kA for 3 seconds tells you it withstands delayed clearing from downstream breakers, so it works as a main or tie breaker in a switchboard where fault-rating coordination is required. The 220 kA making capacity (Icm) covers the worst-case peak asymmetrical fault on a 415 V system. The 25 ms maximum breaking time and 80 ms closing response time are the numbers to plug into your arc-flash study.
Deployment context
The 260 W power dissipation at rated current matters for enclosure cooling calculations; factor that into the switchgear ventilation design.
The H1 performance class is Schneider's designation for 100 kA Icu at 415 V; the Ics equals Icu at all voltage levels up to 690 V, which is unusual and valuable for coordination studies.
