The 3VA1163-5EE32-0CH0 carries a continuous rated current of 63 A at an ambient of 40 °C. That rating holds flat through 50 °C, then begins a controlled derating: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C.
Breaking capacity drops as system voltage rises, which is expected for an MCCB. At 240 V AC the part interrupts 187 kA; at 415 V AC it's 121 kA; at 440 V AC it's 75.6 kA; at 500 V and 690 V AC it holds at 17 kA. The 17 kA floor at 690 V still covers most motor-control applications per IEC 60947-2.
Configuration and auxiliary content
The UVR ensures the breaker drops out on loss of control voltage — a standard requirement for safety circuits in machine tools and conveyors. The auxiliary switch count gives the PLC or DCS a dedicated feedback path for both the breaker position and the trip event, without sharing contacts.
The 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint; it occupies a single 3-module position on the rail.
