Product details

The LV846202 is a MasterPact MTZ2 fixed-mount, 4-pole circuit breaker rated 1250 A at 40 °C — that is the continuous current it carries without tripping in a 40 °C ambient, so for a 35 °C switchroom you get headroom before derating applies. Category B selectivity (per EN/IEC 60947-2) confirms it is designed for that role: it withstands a partial-range fault without opening, letting the branch breaker take the hit.

Deployment context

Fixed-mount on rails or a base plate, with front and rear connection options on both the line and load sides — suits a draw-out-free switchboard where the breaker stays bolted in. IP30 enclosure protection means it is intended for indoor, locked electrical rooms, not washdown areas.

Suitability for isolation per EN/IEC 60947-2 means it provides a visible-break isolation function — no separate disconnect needed upstream.
