At 240 V it interrupts faults up to 187 kA; at 415 V and 440 V that figure holds at 121 kA, dropping to 75.6 kA at 500 V and 9 kA at 690 V. ## Current derating — the real-world rating The 630 A rating applies at 40 °C ambient. At 45 °C the breaker carries 600 A; at 50 °C, 570 A; at 55 °C, 540 A; at 60 °C, 510 A; at 65 °C, 480 A; and at 70 °C, 450 A. ## Physical fit and auxiliary complement The 3-pole frame occupies standard MCCB panel space; verify bus-bar centers and mounting footprint against the existing cutout. The base switch variant is 3VA2463-5JQ32-0AA0; this order code adds the communication function and the auxiliary release.","metaTitle":"Siemens 3VA2463-5JQ32-0HC0 SENTRON MCCB, 630 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2463-5JQ32-0HC0 molded case circuit breaker. 630 A, 3-pole, line protection with shunt trip and communication.
