Overload protection is adjustable: Ir from 88 A to 125 A, so you set the continuous current limit to match the downstream load — a 125 A feeder, for example, or a 100 A motor circuit. Short-circuit pickup Ii is fixed at 5 to 10 times In (625 A to 1250 A at the 125 A setting), which keeps the breaker selective with downstream devices on a typical radial feed. ## Integration notes The TM240 trip unit is non-interchangeable on this variant; verify the Ir setting before installation. The nut keeper kit retains the terminal screws under vibration, a detail worth checking if the panel ships to a site with known harmonic or switching transients.","metaTitle":"Siemens 3VA1112-5EF32-0AA0-ZD00 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA1112-5EF32-0AA0-ZD00 IEC frame 160, class M, Icu=55kA @ 415V, 3-pole, TM240, In=125A, Ir=88A...125A, Ii=5...10 x In.
