That rating holds flat through 50 °C — only above 55 °C does it begin to derate, reaching 583 A at 70 °C. Breaking capacity is specified per voltage: 121 kA at 240 V AC, 76 kA at 415 V and 440 V AC, and 53 kA at 500 V AC. At a typical 480 V industrial service, the interpolated value sits well above 50 kA — enough for most secondary distribution with transformer impedances under 6 %. No ground-fault monitoring or communication function is integrated; this is a straight thermal-magnetic breaker for conventional line protection.
Peer comparison — 3VA1112-5EE32-0AA0
The closest functional peer within the SENTRON family is the 3VA1112-5EE32-0AA0. Both are 3-pole MCCBs with thermal-magnetic releases, but the 3VA1112 is a smaller-frame device rated for lower continuous current — typically 100–250 A range versus this part's 630 A. The 3VM1463-4ED32-0AA0 will not drop into a panel cutout designed for the 3VA1112 frame without busbar and mounting modifications; the footprint and lug spacing differ. Select the 3VM1463-4ED32-0AA0 when the load exceeds 300 A and the fault current at the service point demands the higher interrupting capacity.
