The LV847200 is a Schneider Electric MasterPact MTZ1 drawout circuit breaker, 3-pole, rated 630 A at 40 °C. The Icw of 42 kA for 1 second confirms it withstands delayed-tripping coordination schemes common in selectivity studies. Drawout mounting means the breaker chassis stays wired to the bus while the removable cradle isolates for maintenance or swap — no need to disconnect power cables. Category B selectivity and suitability for isolation (per EN/IEC 60947-2) mean it can serve as the main incoming device in a distribution board where coordination with downstream breakers is required.
Integration notes
The breaker ships without a control unit (specified separately). Mounting support options include rails or a base plate. IP30 enclosure protection is standard; for panel environments with higher dust or moisture ingress, consider an enclosure upgrade. Power dissipation is 55 W — factor this into enclosure thermal calculations, especially in dense switchboards where multiple breakers stack. Altitude derating applies above 2000 m.
Electrical durability is 6000 cycles at 440 V AC (AC-23A) and 3000 cycles at 690 V AC; mechanical durability is 12,500 cycles with periodic preventive maintenance. Maximum breaking time is 25 ms, closing response time 50 ms.
