The Schneider Electric LV848760 is a MasterPact MTZ2 25 HA10 switch disconnector rated for 2500 A at 1150 V AC, 50/60 Hz, with a short-circuit making capacity of 105 kA peak at that voltage. It's a 4-pole drawout unit built to EN/IEC 60947-3, suitable for isolation with a visible break indicator and contact position indicator. The drawout chassis mounting lets you rack the unit in and out for maintenance without disturbing the bus — a standard feature for high-current distribution switchgear.
The 2500 A rated operational current (Ie) at 1150 V AC tells you this unit handles full-load current for large distribution feeders or heavy motor loads in AC-23A and AC-3 duty. AC-23A covers occasional switching of motor loads with inrush; AC-3 covers routine motor starting. The 105 kA peak making capacity (Icm) means it can close onto a fault without welding contacts — critical for coordination in high-fault-current installations. Short-time withstand (Icw) is 50 kA for 1 s or 3 s, giving downstream breakers time to clear before the disconnect takes stress. Rated insulation voltage (Ui) is 1250 V AC, and impulse withstand (Uimp) is 12 kV — these confirm the part is designed for 1150 V systems with margin.
Drawout mounting on a chassis means the unit slides into a fixed cradle with 115 mm connection pitch. Panel cutout must accommodate the 556 mm width, 439 mm height, and 403 mm depth. Push-button control is integral; no separate actuator needed.
