Siemens 3VA2463-5KP32-0JL0 is a SENTRON molded case circuit breaker rated for 630 A continuous at 40 °C, with a 3-pole configuration and an adjustable trip covering 945 A to 5 670 A.
What the ratings mean for your panel
The 630 A frame at 40 °C is the thermal baseline; above that ambient the breaker must be derated — 600 A at 45 °C, 570 A at 50 °C, and stepping down to 450 A at 70 °C. If your enclosure runs hot, the continuous current you can actually carry is the derated figure, not the nameplate. The adjustable trip range (945 A minimum to 5 670 A maximum) lets you coordinate selectively with downstream breakers. Set the magnetic pickup high enough to ride through motor inrush without nuisance trips, but within the frame's SCCR envelope at your system voltage. Interrupting capacity of 187 kA at 240 V and 121 kA at 415 V means this breaker can safely clear a bolted fault at those levels without rupturing. At 690 V the rating drops to 9 kA — verify your available fault current at that voltage before specifying.
Integration and accessories
The breaker ships with a shunt trip release (STL) and a complement of auxiliary switches: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ configuration). A communication function is built in, supporting integration with higher-level monitoring systems. Dimensions are 248 mm high × 138 mm wide × 110 mm deep — a standard SENTRON 3VA frame footprint that fits existing panel cutouts for the series. The 3-pole body accepts line and load lugs for 630 A cable or bus bar. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. Power loss at full load is 162 W maximum — account for that heat in your enclosure sizing and ventilation.
