The Siemens SENTRON 3VA2463-5HL32-0KH0 is a 3-pole molded case circuit breaker rated for 630 A continuous current, with a maximum interrupting capacity of 187 kA at 240 V AC and 121 kA at 415/440 V. The interrupting curve drops to 75.6 kA at 500 V and 9 kA at 690 V, so verify your system voltage against the table before specifying. This breaker carries a line protection design (not motor protection), meaning the trip curve is fixed for feeder and distribution duty — no adjustable overload class for motor starting inrush. The continuous rating of 630 A at 40 °C derates to 520 A at 70 °C; if your panel ambient runs hot, size the upstream conductor for the derated value, not the nameplate 630 A.
At 138 mm wide, 248 mm tall, and 110 mm deep, this MCCB fits standard SENTRON 3VA switchboard mounting patterns. The 138 mm width (5.43 in) occupies three pole spaces on a standard DIN-rail or busbar system.
