It's the frame that receives the breaker cassette in a drawout installation — the part that bolts to the bus and carries the primary disconnects. The 800 A floor on the rated operational current means it's sized for the MTZ2 frame's lower band; the 2000 A ceiling matches the standard MTZ2 breaker ratings up to that level. UL/ANSI listed per the description, so it's accepted for North American panel builds without additional agency evaluation. ## Integration Note Drawout mounting means the cradle stays in the switchgear cubicle while the breaker cassette slides in and out on telescoping rails. The 3-pole configuration matches three-phase power distribution in LV switchboards. Rated operational current spans 800-2000 A at 104 °F (40 °C) — the thermal derating above that ambient is on the breaker, not the cradle, but the cradle's continuous-current path is the same copper cluster. Verify the cradle's horizontal/vertical bus connection orientation against your switchboard layout before ordering; the MTZ2 cradle ships as a mounting accessory, not a breaker, so the bus stabs and secondary disconnect blocks are part of this assembly.","metaTitle":"Schneider Electric LV839333 MasterPact MTZ2 Cradle, 3P Drawo","metaDescription":"Schneider Electric LV839333 MasterPact MTZ2 cradle, 3-pole drawout, rated 800-2000 A at 104 °F (40 °C).
