MasterPact MTZ2 16 HA10 — 1600 A Switch Disconnector for Distribution
The LV848758 is a Schneider Electric MasterPact MTZ2 16 HA10 switch disconnector rated for 1600 A continuous current at 1150 V AC, 50/60 Hz, in a 4-pole drawout chassis configuration. The part is built to EN/IEC 60947-3 and is certified for isolation (visible-break indicator confirms the contacts are open).
Short-Time Withstand and Fault Coordination
Rated short-time withstand current (Icw) is 50 kA for both 1 s and 3 s durations — a 3 s rating that gives downstream protection devices time to clear without stressing the switch. Utilisation categories AC-23A and AC-3 cover switching of motor loads and mixed resistive-inductive circuits, though at 1600 A this is primarily a distribution disconnect rather than a motor starter.
Drawout Construction and Panel Integration
Drawout mounting (chassis-supported) allows the switch to be racked out for maintenance or replacement without disturbing the main bus connections — a standard requirement for main breakers in switchgear lineups. Physical footprint: 556 mm wide × 439 mm high × 403 mm deep. Connection pitch is 115 mm. IP30 protection means it is intended for enclosed panel installation, not open washdown areas. Mechanical durability is rated at 25,000 cycles with periodic preventive maintenance; electrical durability is 500 cycles at full rated voltage in AC-23A duty — a disconnect that is not cycled daily, but is robust for infrequent switching.
