The unit includes an undervoltage release and two HQ auxiliary switches, and it's rated IP40 on the front, meaning it keeps dust out of the panel face but isn't meant for washdown environments. The 250 A rating holds steady from 40 °C up to 50 °C, then starts to derate: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C. The 15 000-cycle latching endurance tells you it's rated for frequent switching, not just backup protection. The IP40 front rating means it's fine for enclosed panels; keep it out of direct spray.","metaTitle":"Siemens 3VA1225-4EF32-0CC0 SENTRON MCCB, 250 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1225-4EF32-0CC0 molded case circuit breaker, 250 A continuous, 3-pole, breaking capacity 121 kA at 240 V AC.
