The LV847260 is a MasterPact MTZ2 08 HA10 switch-disconnector rated 800 A continuous at 1150 V AC, 50/60 Hz, with a short-circuit making capacity of 105 kA peak at that voltage. The 50 kA Icw for 1 s (and 3 s) means it holds through a delayed trip coordination, so it works with selective breaker schemes downstream. Rated insulation voltage is 1250 V, impulse withstand 12 kV — it's built for 690 V class systems with margin, or 1000 V industrial grids. Utilisation categories AC-23A and AC-3 cover switching of motor loads with occasional inrush (AC-3) and mixed resistive-inductive loads including occasional motor starting (AC-23A). The 800 A frame handles large motors, transformers, or main feeders. Fixed mounting, 3-pole, push-button control, no visible break — this is a panel-mounted disconnect, not a plug-in unit.
Deployment context
This switch-disconnector lives in a fixed-mount enclosure — typically a distribution panel or motor control centre. The 422 mm width, 352 mm height, and 300 mm depth tell you the cubicle cutout and backpanel space needed. IP30 protection means it's for indoor, clean environments; not washdown or outdoor without an enclosure.
