What this switch disconnector handles
The LV847263 is a fixed-mount, 3-pole MasterPact MTZ2 16 HA10 switch disconnector rated for 1600 A continuous at 1150 V AC, 50/60 Hz. That 1600 A figure is the rated operational current (Ie) in AC-23A and AC-3 utilisation categories — meaning it's sized for heavy motor switching and mixed resistive-inductive loads, not just passive distribution. It carries a rated short-time withstand current (Icw) of 50 kA for 3 seconds, so it holds through delayed-trip coordination windows downstream. Rated impulse withstand voltage is 12 kV (Uimp), and rated insulation voltage is 1250 V (Ui). All ratings conform to EN/IEC 60947-3, and the device is marked suitable for isolation per that standard — the contact position indicator and visible-break confirmation (none here, but the indicator satisfies the isolation requirement) back that up.
Fixed-mount chassis, 422 mm wide by 352 mm high by 300 mm deep. Connection pitch is 115 mm between phases. IP30 front means tools or fingers won't reach live parts, but it's not sealed against water ingress — install in a clean, dry enclosure. Mechanical endurance is 25,000 cycles with periodic preventive maintenance per EN/IEC 60947-3.
