Product details

MasterPact MTZ2 2500 A — fixed-mount power breaker

The Schneider Electric LV848079 is a MasterPact MTZ2 25 H2 fixed-mount circuit breaker, rated 2500 A at 40 °C with a 4-pole configuration. Category B selectivity means it coordinates with downstream breakers to isolate faults without blacking out upstream feeders, critical for service continuity in industrial switchboards.

Breaking performance and withstand

Service breaking capacity (Ics) holds 100 kA at 220/415 V and 440 V, derating to 85 kA at 500/525 V and 85 kA at 660/690 V. Short-time withstand (Icw) is 85 kA for 1 s, 75 kA for 3 s — the sustained fault window a downstream relay might need to clear. Making capacity (Icm) peaks at 220 kA at 415 V. Maximum total break time is 25 ms; closing response is 70 ms. These numbers define the SCCR headroom for coordination studies.

Insulation and environment

Rated insulation voltage (Ui) is 1000 V AC, operational voltage (Ue) 690 V AC, with an impulse withstand (Uimp) of 12 kV. Connection pitch is 115 mm. Operating range is -25 to 70 °C, storage -40 to 85 °C, altitude up to 2000 m without derating.

Frequently asked questions
