The 20 A rating holds flat from 40 °C to 50 °C, then derates to 19.2 A at 55 °C and 18 A at 70 °C. The IP40 front protection means it's splash-safe from the front in a typical enclosed panel; no outdoor or washdown rating. Mechanical endurance is 15,000 operations — that's a standard figure for a fixed-mounted MCCB in a distribution board where it cycles a few times a year, not a motor-starting duty cycle.","metaTitle":"Siemens 3VA1020-2ED36-0AF0 SENTRON MCCB, 20 A, 52.5 kA","metaDescription":"Siemens SENTRON 3VA1020-2ED36-0AF0 molded case circuit breaker, 3-pole, 20 A, breaking capacity 52.5 kA at 240 V.
