That's a clean, linear derate — no cliff. If your panel hits 60 °C (common in enclosed MCCs with transformer heat), you're working with 232 A continuous, not 250. Plan the branch circuit load accordingly. Maximum power loss is 48 W — that's the heat the breaker dumps into the enclosure at full load, so factor it into your thermal budget.","metaTitle":"Siemens 3VA2225-7HL32-0AJ0 SENTRON MCCB, 250 A, 3-Pole, Line","metaDescription":"Siemens 3VA2225-7HL32-0AJ0 SENTRON molded case circuit breaker, 250 A rated continuous current, 3-pole, ETU320 trip unit, line protection.
