Breaking capacity is 187 kA at 240 V AC, derating to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. The 3VA2163-5MN32-0CC0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA footprint that fits Siemens panel-mounting systems and most third-party enclosures with a compatible cutout. Front-face protection is IP40, so the breaker is suited for dry indoor panel environments; no washdown or outdoor rating applies. ## Thermal derating curve Above that, the rated continuous current derates linearly: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. If the panel ambient exceeds 50 °C, the load current must be reduced accordingly — the breaker will not trip falsely, but the continuous rating is the thermal limit of the internal bimetal and electronics. Maximum power dissipation is 75 W at rated load.","metaTitle":"Siemens 3VA2163-5MN32-0CC0 MCCB, 63 A, 187 kA at 240 V","metaDescription":"Siemens SENTRON 3VA2163-5MN32-0CC0 molded case circuit breaker, 63 A rated, 187 kA breaking at 240 V.
