That 70 °C figure matches the maximum operating temperature of the breaker itself, so if your panel ambient is near that limit you lose nearly 30 % of the rated current. Plan the enclosure ventilation or upsizing accordingly — this breaker's frame can handle the heat, but the trip unit follows the published curve. The 138 mm width for a 3-pole 630 A frame is standard for this class.","metaTitle":"Siemens 3VA2463-5JP32-0AC0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens 3VA2463-5JP32-0AC0 SENTRON molded case circuit breaker, 630 A rated, 3-pole, line protection, 187 kA breaking at 240 V.
