Category B selectivity means it coordinates with downstream breakers to isolate only the faulted branch — critical for maintaining uptime on a distribution bus feeding multiple loads. This is a drawout-mount breaker (with chassis: 403 mm deep, 556 mm wide, 439 mm high; without chassis: 300 mm deep, 493 mm wide, 300 mm high), designed for switchboard installation where the breaker can be racked out for maintenance without de-energizing the bus. ## Breaking capacity and withstand Rated service breaking capacity Ics is 66 kA at 220/415 V, 440 V, 500/525 V, and 660/690 V AC — flat across the voltage band, so no derating needed as you move up to 690 V. The rated short-time withstand Icw holds 66 kA for 3 seconds, giving downstream protection devices time to clear a fault before the main breaker trips. Making capacity Icm is 145 kA at all listed voltages. Maximum breaking time is 25 ms; maximum closing response time is 70 ms. Standards compliance includes EN/IEC 60947-1, EN/IEC 60947-2 (including Annex H for EMC), and IEC 61557-12 for power metering. Drawout mounting with front or rear connection on both upside and downside. Connection pitch is 150 mm. Mounting support options include rails or base plate. Neutral position is on the right. IP30 protection per EN 60529 — suitable for enclosed switchgear, not for washdown environments. Operating altitude 0–2000 m without derating, 2000–5000 m with derating. Power dissipation is 900 W at rated current. ## Durability and ratings Electrical durability varies by duty: 6000 cycles at 440/690 V AC in AC-3 (motor switching), 5000 cycles at 440 V in AC-1 (resistive), 2500 cycles at 690 V in AC-23A (high-stress motor or mixed loads). Sensor rating options cover 2000 A, 2500 A, 3200 A, and 4000 A — the 4000 A frame allows future upsizing without swapping the breaker chassis.","metaTitle":"Schneider Electric LV848332 MasterPact MTZ2 4000 A Drawout C","metaDescription":"Schneider Electric LV848332 MasterPact MTZ2 4P drawout circuit breaker, rated 4000 A at 40 °C, 66 kA Ics at 415-690 V AC.
