It is the H1 performance variant, delivering 100 kA Icu at 415 V AC, with the same 100 kA across the full voltage range up to 690 V AC. The drawout chassis (included) lets you rack the breaker between connected, test, and disconnected positions without pulling cables, a standard requirement for main breakers that need periodic maintenance access. ## Ratings that matter for the switchboard designer The short-time withstand current (Icw) is 100 kA for 0.5 s, 1 s, and 3 s. Category B selectivity confirms it is designed for that role. Making capacity (Icm) is 220 kA at 415 V. This is the peak asymmetrical current the breaker can close into and latch against. Maximum closing response time is 80 ms. Insulation voltage (Ui) is 1000 V AC, operational voltage (Ue) is 690 V AC, and impulse withstand (Uimp) is 12 kV. Drawout configuration with chassis: 403 mm deep, 1016 mm wide, 479 mm high. Without chassis: 300 mm deep, 838 mm wide, 300 mm high. The 230 mm connection pitch determines bus-bar drilling on the rear-connected pads — both upside and downside connections are rear. Mounting support options are rails or base plate. Neutral position is on the right. Standard for MasterPact 4P frames; verify bus-bar phasing if your switchboard is laid out left-neutral. These are the core IEC standards for low-voltage switchgear and controlgear. No UL or CSA listing appears in the evidence; for North American projects, verify acceptance with the local code authority. ## Environmental and durability Altitude derating applies above 2000 m — up to 5000 m with derating. Power dissipation at rated current is 600 W — that is the heat the switchgear ventilation must extract. Mechanical durability is 10,000 cycles with periodic preventive maintenance. Electrical durability varies by duty: 6000 cycles for AC-3 (motor switching) at 440/690 V, 1500 cycles for AC-23A (occasional motor switching including inching) at the same voltages.","metaTitle":"Schneider Electric LV848333 MasterPact MTZ3 4000 A Drawout C","metaDescription":"Schneider Electric LV848333 MasterPact MTZ3 4000 A drawout circuit breaker.
