It is a Category B breaker (selectivity type) per EN/IEC 60947-2, meaning it coordinates with downstream devices to isolate only the faulted branch during a short circuit — critical for maintaining power to healthy loads in a distribution panel. ## Breaking capacity and fault handling Rated service breaking capacity (Ics) is 100 kA at both 220/415 V AC and 440 V AC, so the breaker can clear a fault and be reclosed without replacement. Short-time withstand (Icw) holds 100 kA for 1 second — enough for selective coordination with upstream gear. Making capacity (Icm) reaches 220 kA at 440 V AC, covering the peak asymmetrical current on a bolted fault. Maximum total break time is 25 ms; closing response is 70 ms. Fixed-mount chassis, 537 mm wide x 352 mm high x 300 mm deep. Connection pitch is 115 mm. Both upside and downside connections accept front or rear terminations — choose based on switchboard bus run. Mounting support is rails or base plate; neutral is on the right. IP30 enclosure suits indoor switchgear; pollution degree 3 per IEC 60947-1 means it tolerates conductive dust in industrial environments.","metaTitle":"LV846207 MasterPact MTZ2 4000A Circuit Breaker, 100 kA","metaDescription":"LV846207 MasterPact MTZ2 4P fixed circuit breaker, 4000 A at 40 °C, 100 kA breaking capacity at 440 V AC.
