The LV848755 is a MasterPact MTZ2 08 HA10 switch disconnector rated for 800 A continuous at 1150 V AC, 50/60 Hz, with a short-circuit making capacity of 105 kA peak at that voltage. Four poles, drawout mounting on a chassis. It carries AC-23A and AC-3 utilisation categories, meaning it handles motor switching and mixed resistive-inductive loads up to its full rating.
Rated short-time withstand current is 50 kA for 1 s and also for 3 s per EN/IEC 60947-3 — the 3-second window is unusual and gives coordination flexibility on high-fault panels where upstream clearing times are slower. Insulation voltage is 1250 V, impulse withstand 12 kV. Mechanical durability is 25,000 cycles with periodic preventive maintenance; electrical durability under AC-23A at 1150 V is 500 cycles. That electrical endurance figure is low — this is a distribution disconnect, not a daily-operating switch. It's sized for infrequent load-break or isolation duty where the contact wear budget matches the maintenance interval. No visible break gap, so the indicator is the positive confirmation of open contacts. IP30 enclosure protection — panel-mounted, not for washdown areas.
