The 200 A rating holds flat from 40 °C through 50 °C, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C — useful to know if the breaker lands in a warm enclosure or next to other heat sources. No auxiliary contact module is fitted as standard; if you need a remote status signal, plan to add one.","metaTitle":"Siemens 3VA1220-5EF32-0JA0 SENTRON MCCB, 200 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1220-5EF32-0JA0 molded case circuit breaker, 200 A rated, 3-pole, line protection.
