The SENTRON 3VA1463-6EE32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 630 A continuous current at 40 °C, with a TM220 thermal-magnetic overcurrent release. It is designed for line protection — the primary role is protecting cables and busbars from overloads and short circuits in distribution panels.
Continuous current holds at 630 A from 40 °C through 50 °C ambient, then derates linearly to 583 A at 70 °C. The TM220 release handles the overload curve; the magnetic element trips instantaneously on short-circuit. Breaking capacity varies by voltage: 220 kA at 240 V, 154 kA at 415 V and 440 V, 121 kA at 500 V, and 17 kA at 690 V.
