The LV848751 is a MasterPact MTZ2 32 HA10 switch-disconnector rated for 3200 A at 1150 V AC 50/60 Hz. Three-pole drawout chassis mount, push-button control. Suited for distribution applications where you need a visible-break isolation point that can also handle motor switching duty (AC-23A / AC-3 utilization). Rated short-time withstand current (Icw) is 50 kA for 1 s and 50 kA for 3 s per EN/IEC 60947-3. Making capacity (Icm) hits 105 kA peak at 1150 V. Impulse withstand voltage (Uimp) is 12 kV. Insulation voltage (Ui) is 1250 V AC. That puts it in the heavy industrial class — main incomer or large feeder duty. Electrical durability is 500 cycles at 1150 V AC in AC-23A. Not a daily-switching part — it's sized for isolation and fault making/breaking, not frequent motor starts.
Drawout mounting on a chassis — 441 mm wide, 439 mm high, 403 mm deep. Connection pitch is 115 mm. Pollution degree 3 per EN/IEC 60947-4-1. That means it's designed for a controlled electrical room, not a washdown floor. IP30 enclosure rating — open panel, not sealed. Contact position indicator shows open/closed state.
