This is a Category B breaker (selectivity type) per IEC 60947-2, meaning it's designed for full discrimination in distribution networks — a fault downstream won't trip the upstream breaker, which is the main requirement for coordinating a plant main or a feeder in a tiered power system. The drawout chassis lets you rack the breaker out for maintenance or replacement without disturbing the bus connections — a standard requirement for switchgear where uptime matters. Mounting support is on rails or base plate, with front or rear connection on both the line and load sides. The 115 mm connection pitch matches standard switchgear busbar spacing. The Icw short-time withstand is 66 kA for 1 second (36 kA for 3 s), which gives downstream protection devices time to clear a fault before the main trips. That 1-second window is the selectivity time band you design around when setting up zone interlocking or time-delay coordination with feeder breakers. The making capacity Icm hits 145 kA at 415 V — that's the peak let-through the breaker can close into without welding contacts. Rated insulation voltage is 1000 V AC, operational voltage 690 V AC, with a 12 kV impulse withstand. ## Physical Fit and Deployment Context With the drawout chassis installed, the breaker footprint is 556 mm wide × 439 mm high × 403 mm deep. Without the chassis (for handling or storage), it's 493 mm × 300 mm × 300 mm. The IP30 enclosure protection is standard for indoor switchgear — not washdown-rated, but fine for a clean electrical room. Altitude derating starts above 2000 m. ## Sensor Ratings and Control Configuration The sensor rating for this frame covers 1000 A, 1250 A, 1600 A, and 2000 A — the breaker ships with the 2000 A rating as standard, but the same frame accepts lower-rated sensors if a future re-rate is needed. Control is push-button type with no separate control unit; the neutral position is on the right for a 4-pole configuration. Power dissipation at rated current is 470 W — relevant for enclosure ventilation calculations.","metaTitle":"Schneider Electric LV848436 MasterPact MTZ2 20 H1 Drawout Br","metaDescription":"Schneider LV848436 MasterPact MTZ2 20 H1 drawout circuit breaker, 2000 A at 40 °C, 66 kA breaking capacity, 4P.
