Breaking capacity scales with system voltage: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. This covers most low-voltage distribution networks from 240 V single-phase through 690 V three-phase. ## Thermal derating curve Continuous current rating derates with ambient temperature: 630 A at 40 °C, 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. For a panel running at 50 °C ambient, plan for 570 A continuous — roughly 10% below the 40 °C nameplate. The 138 mm width fits standard 3-pole MCCB mounting footprints in distribution boards. Maximum power dissipation is 162 W — factor this into enclosure thermal calculations to avoid derating the breaker by its own heat.","metaTitle":"Siemens 3VA2463-5KP32-0AH0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens 3VA2463-5KP32-0AH0 SENTRON molded case circuit breaker, 630 A at 40 °C, 3-pole, 187 kA at 240 V.
