The Schneider Electric LV848745 is a MasterPact MTZ2 08 HA10 switch-disconnector, rated 800 A continuous at 1150 V AC in a 3-pole drawout chassis. It is built to EN/IEC 60947-3 for isolation and switching duty, with a utilisation category of AC-23A (motor switching with occasional inrush) and AC-3 (squirrel-cage motor starting/stopping). The 50 kA short-time withstand for 1 s (and 3 s) means it can ride through a bolted fault without welding contacts — critical for selective coordination in a distribution panel. The 105 kA peak making capacity handles the first asymmetric half-cycle of a short-circuit without contact bounce.
Drawout chassis and panel integration
Drawout mounting means the switching element slides out of its cradle for inspection or swap without disconnecting power cables — a standard requirement for main or tie breakers in a switchboard. The chassis mount bolts into a dedicated cell; connection pitch is 115 mm. Overall dimensions: 441 mm wide × 439 mm high × 403 mm deep.
The LV848745 carries an active lifecycle status. It is a current-production catalog item in the MasterPact MTZ2 family. No official successor has been issued — this is the current generation.
Rated insulation voltage (Ui): 1250 V AC. Impulse withstand (Uimp): 12 kV. Electrical durability: 500 cycles at 1150 V under AC-23A. Mechanical durability: 25000 cycles with periodic preventive maintenance.
