The Siemens SENTRON 3VA2463-5JP32-0KL0 is a 3-pole molded case circuit breaker (MCCB) rated for 630 A continuous current at 40 °C, with a maximum breaking capacity of 187 kA at 240 V. It is designed for line protection in industrial distribution panels and carries a communication function for integration into higher-level monitoring systems.
Breaking capacity and thermal derating
Breaking capacity drops from 187 kA at 240 V to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 9 kA at 690 V — so at higher nominal voltages the available fault current must be verified against the installation's prospective short-circuit current. Continuous current derates from 630 A at 40 °C down to 450 A at 70 °C; the 162 W maximum power loss at full load should be factored into enclosure thermal calculations.
Integration notes
Dimensions are 138 mm wide, 248 mm high, and 110 mm deep — fits standard panel cutouts for this frame size. The auxiliary switch configuration includes 2 auxiliary switches plus 1 trip alarm and 1 electrical alarm switch (HQ), and a shunt trip (STL) release is built in. No undervoltage release is fitted; no ground-fault monitoring version. The basic switch module is order code 3VA2463-5JP32-0AA0.
