It is designed for main or feeder protection in low-voltage power distribution, typically installed in switchgear lineups where drawout construction allows racking the breaker out for maintenance without de-energizing the bus. The Category B selectivity rating means it coordinates with downstream devices to isolate only the faulted branch, keeping the rest of the plant online. At 690 V AC the Ics drops to 85 kA, still substantial for industrial feeds. The rated short-time withstand current (Icw) is 85 kA for 1 second and 75 kA for 3 seconds, which matters for selective coordination: downstream breakers need time to clear before this one trips, and the Icw rating guarantees the breaker holds closed under fault current for that duration. Making capacity (Icm) peaks at 220 kA at 415 V, covering the asymmetrical first peak of a short circuit. ## Dimensions and mounting — panel integration notes Drawout configuration with chassis: 403 mm deep, 556 mm wide, 439 mm tall. Without chassis the breaker itself is 300 mm deep and 493 mm wide. The 115 mm connection pitch and front/rear connection options give flexibility in cabinet layout — useful when retrofitting into an existing switchgear lineup where bus bar centers are already set. Mounting support is rails or base plate, typical for withdrawable chassis installation. IP30 protection means the breaker is protected against tools and wires >2.5 mm but is not sealed against dust ingress; the enclosure provides the environmental seal. Also complies with IEC 61557-12 for insulation monitoring. Altitude derating applies above 2000 m. ## Durability and maintenance planning Electrical durability varies by duty: 6000 cycles at 440/690 V AC in AC-3 (motor switching), 5000 cycles at 440 V under EN/IEC 60947-2, and 2500 cycles at 690 V. For a main breaker that operates infrequently (a few times per year for maintenance switching), this is effectively a lifetime rating. Power dissipation is 600 W at rated current — account for this in enclosure ventilation design to avoid derating.","metaTitle":"Schneider Electric LV848309 MasterPact MTZ2 2500 A Drawout B","metaDescription":"Schneider Electric LV848309 MasterPact MTZ2 2500 A drawout circuit breaker. 100 kA at 415 V AC, IEC 60947, 4P.
