The Schneider Electric LV847273 is a MasterPact MTZ2 16 HA10 switch disconnector, rated for 1600 A at 1150 V AC 50/60 Hz — sized for high-current distribution and motor isolation in industrial switchboards. It carries a short-circuit making capacity of 105 kA peak at 1150 V, so it can close onto a fault without welding contacts, which matters for feeder protection in high-fault installations. The 4-pole fixed-mount design suits main incomer or bus-tie positions where visible isolation is not required (no visible break).
Ratings and compliance
Built to EN/IEC 60947-3, the LV847273 is certified for isolation (suitability for isolation: Yes), meaning the open contacts provide the safety gap required for lockout/tagout on the line side. The rated impulse withstand voltage is 12 kV, and the short-time withstand current is 50 kA for 1 s or 3 s — enough to coordinate with upstream breakers in a selective scheme. Utilisation categories AC-23A and AC-3 cover switching of motor loads and mixed resistive-inductive loads, though the 1600 A frame is oversized for most motors and typically serves a distribution bus. Pollution degree 3 (conforming to EN/IEC 60947-4-1) means it tolerates conductive dust in industrial enclosures.
