The 4-pole drawout chassis mount suits main or tie-breaker positions in low-voltage switchgear where full isolation and visible-break indication are required — the part is certified for isolation per EN/IEC 60947-3 and carries a contact position indicator. The drawout design means the moving portion can be racked out for maintenance without disturbing line or load connections, a standard requirement for main incomers in industrial and utility distribution. Pollution degree 3 per EN/IEC 60947-4-1 confirms it holds up in dusty or conductive-contaminant environments typical of panel rooms. ## Breaking capacity and duty ratings Rated Icu at 220/415 V and 440 V is 100 kA; the Ics (service breaking capacity) matches at 100 kA across the same voltages, meaning the switch can clear a fault and be returned to service without derating. Short-time withstand (Icw) is 75 kA for 3 s or 100 kA for 1 s, giving selectivity headroom for downstream breakers. Making capacity (Icm) peaks at 220 kA at 440 V — relevant for closing onto a bolted fault. Utilisation categories AC-23A and AC-3 cover switching of motor loads and mixed resistive-inductive loads; electrical endurance is 5000 cycles at 440 V under AC-23A. Mechanical durability is 15,000 cycles with periodic preventive maintenance. ## Physical and environmental Dimensions: 556 mm wide, 439 mm high, 403 mm deep. Mounting is drawout on a chassis support with a 115 mm connection pitch.","metaTitle":"Schneider Electric LV846349 MasterPact MTZ2 40HH Switch Disc","metaDescription":"Schneider Electric LV846349 MasterPact MTZ2 40HH switch disconnector, 4000A, 100kA Icu at 440V, 4P drawout.
