The Schneider Electric LV846185 is a MasterPact MTZ2 air circuit breaker, 4 poles, fixed-mounted, with a rated current of 2500 A at 40 °C. Category B selectivity per IEC 60947-2 confirms it's designed for full discrimination with downstream breakers, so a fault on a branch won't take the main bus down.
The short-time withstand current (Icw) is 100 kA for 0.5 s and 1 s, and 75 kA for 3 s; that's the current the breaker can carry without damage during a delayed trip, critical for selective coordination with downstream MCCBs. Making capacity (Icm) is 220 kA at 440 V AC — the peak let-through it can close into a short circuit.
Fixed-mount chassis, 4-pole, with front and rear connection options on both upside and downside. Overall dimensions: width 537 mm, height 352 mm, depth 300 mm. Connection pitch is 115 mm.
The breaker carries the CE marking for the European market. For RoHS, REACH, and UL documentation, the manufacturer provides declarations on request — the evidence does not list specific UL file numbers or RoHS exemption dates, so verify with the factory for your jurisdiction.
