Category B selectivity (per IEC 60947-2) means it's designed for selective coordination downstream, so a fault on a branch trips the branch breaker, not this main. The 100 kA Icw for 1 second tells you it can pass through a delayed fault current without damage, critical for motor-starting or transformer-inrush scenarios where the breaker must hold closed during the transient. The 170 W power dissipation at rated current matters for panel thermal management — that's heat that must be vented or the enclosure derated. IP30 protection means it's for indoor switchboards, not washdown environments. The 25 ms maximum breaking time and 70 ms closing response give the protection engineer numbers for arc-flash incident energy calculations and coordination studies. ## Deployment context Fixed-mount design with front and rear connection options on both upside and downside. Mounts on rails or a base plate — typical for a main incoming breaker in a low-voltage switchboard. Neutral is on the right. Compliant with EN/IEC 60947-1, EN/IEC 60947-2, EN/IEC 60947-2 Annex H, and IEC 61557-12.","metaTitle":"Schneider Electric LV846203 MasterPact MTZ2 1600A 4P Circuit","metaDescription":"Schneider Electric LV846203 MasterPact MTZ2 circuit breaker, 1600 A rated at 40 °C, 4 poles, 100 kA breaking capacity at 440 V AC.
