The line-protection design means the thermal-magnetic trip curve is calibrated for cable and busbar protection rather than motor overload, so pair it with a separate motor-protective device downstream if feeding a motor load. This unit includes a communication function and other measurement functions, so it can report current draw and trip events over a bus — useful for a facility monitoring system or a power-management scheme. The auxiliary switch configuration carries two HQ auxiliary switches plus a shunt trip release (STL), giving remote open/close status and a remote-trip capability without adding an external undervoltage module. The continuous current rating drops from 630 A at 40 °C to 450 A at 70 °C (–). For a panel that runs warm — say 50 °C ambient inside the enclosure — the usable rating is 570 A, so size the upstream transformer and busbars accordingly. Maximum power loss is 162 W; that heat needs to be factored into the enclosure ventilation, especially if the breaker is enclosed in a non-ventilated cabinet with other heat sources.","metaTitle":"Siemens 3VA2463-5KP32-0KC0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0KC0 molded case circuit breaker, 630 A continuous, 3-pole, 187 kA at 240 V.
