For a panel near a tire-curing press where ambient can push 50–55 °C, the effective rating drops to 540–570 A, so size the upstream transformer and bus accordingly. At 240 V it handles 187 kA; at 415 V and 440 V it handles 121 kA; at 500 V it handles 75.6 kA; at 690 V it handles 9 kA. The communication function allows remote monitoring or trip indication over a fieldbus, though the protocol is not specified in the base listing; verify compatibility with your PLC or BMS gateway. Maximum power loss is 164.5 W at full rated current. That heat must be dissipated inside the enclosure; for a panel with multiple breakers, factor this into the thermal budget to avoid cascading derating.","metaTitle":"Siemens 3VA2463-5KP32-0CH0 SENTRON MCCB, 630A, 3-Pole, 187kA","metaDescription":"Siemens 3VA2463-5KP32-0CH0 SENTRON molded case circuit breaker, 630A continuous at 40°C, 3-pole, 187kA breaking at 240V.
