The Siemens SENTRON 3VA2463-6JP32-0AC0 is a 3-pole molded case circuit breaker rated for a continuous current Iu of 630 A at 40 °C, with a maximum breaking capacity of 242 kA at 240 V AC. That interrupting rating drops to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V — so the available fault current at the installation point decides the fit, not the headline number.
Thermal derating and panel space
Above that, derate linearly: 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C.
Trip unit and auxiliary contacts
It draws power from the breaker's own current path, so no external control power is needed for the trip function. The two HQ auxiliary switches provide normally-open/normally-closed contact status for remote monitoring. No undervoltage release or shunt trip is fitted on this variant (the order code ends in 0AC0, which omits those).
