The 250 A rating holds steady up to 50 °C, then derates to 241 A at 55 °C and 213 A at 70 °C, which means you don't lose headroom until the panel ambient climbs above 50 °C — useful in a hot MCC room or near process heat.","metaTitle":"Siemens 3VA2225-5HN42-0AJ0 SENTRON MCCB, 250 A, 187 kA at 24","metaDescription":"Siemens 3VA2225-5HN42-0AJ0 SENTRON molded case circuit breaker, 250 A rated, 4-pole, line protection.
