The LV847264 is a Schneider Electric MasterPact MTZ2 20 HA10 switch disconnector rated 2000 A at 1150 V AC, 50/60 Hz. It is a 3-pole, fixed-mount unit with a push-button control and a visible break indicator, certified for isolation per EN/IEC 60947-3. The 2000 A continuous rating means it can serve as the main disconnect for a large distribution board or high-current feeder circuit without derating at its rated voltage.
Short-circuit performance and duty
The short-circuit making capacity (Icm) is 105 kA peak at 1150 V AC, and the short-time withstand (Icw) is 50 kA for 1 s or 3 s. That 50 kA for 3 s figure is unusual — most switches manage 1 s at that level. It gives the protection engineer real selectivity headroom when coordinating with upstream breakers or fuses.
Duty cycles and environment
Electrical durability for AC-23A duty is 500 cycles at 1150 V — this is a disconnect, not a daily switching contactor. The operating temperature range is -25 to 70 °C, storage -40 to 85 °C, with IP30 protection (finger-safe front, open back for panel mounting).
