It's a 3-pole unit, performance type H10, built for power distribution protection in industrial switchgear. It's a Category B breaker, meaning it's designed for selectivity — it can hold a short-time withstand current (Icw) of 50 kA for up to 3 seconds, letting downstream devices clear a fault before this one trips. That's critical for maintaining power to healthy circuits in a distribution board. The 260 W power dissipation is heat you have to vent. In a closed panel, that adds up — derate adjacent devices and ensure airflow, especially if you're packing multiple breakers side by side. Fixed mounting on rails or a base plate. Rear connections both top and bottom — plan your busbar runs and cable entry accordingly. The 115 mm connection pitch gives you the hole spacing for drilling gland plates or busbar supports. Dimensions: 422 mm wide × 352 mm high × 300 mm deep. The 300 mm depth is the key fit dimension for enclosure depth — make sure your cabinet has at least that plus clearance for rear connections and arc-chute exhaust.","metaTitle":"LV846545 MasterPact MTZ2 3P 2500A Circuit Breaker, Icu 50kA","metaDescription":"LV846545 MasterPact MTZ2 fixed circuit breaker, 2500 A at 40 °C, Icu 50 kA at 1150 V AC.
