For a panel feeding a tire-curing press or a DC power OEM line, that 36 kA rating means the breaker holds up to the steam-side fault levels without upstream coordination headaches. The short-circuit protection is fixed at Ii = 16 × In, so the magnetic trip fires at 320 A. That is a deliberate choice: high inrush loads (motors, transformers, DC bus capacitors) pass through without nuisance trips, but a hard fault still clears fast. The overload protection Ir is fixed at 20 A — no adjustment range on this variant.","metaTitle":"Siemens 3VA1020-4ED32-0AA0-ZD00 Circuit Breaker, 20A, 36kA @","metaDescription":"Siemens 3VA1020-4ED32-0AA0-ZD00 IEC frame 100 circuit breaker, 3-pole, 20A, 36kA breaking capacity @ 415V.
