The SENTRON 3VA2463-6HL32-0CL0 is a 3-pole molded case circuit breaker rated for 630 A continuous current at 40 °C, designed for line protection in distribution panels. Its breaking capacity is 242 kA at 240 V and 187 kA at 415 V, which means it can safely interrupt fault currents up to those levels without upstream devices needing to clear the fault — critical for high-fault installations like transformer secondaries or large motor control centers. The thermal derating curve runs from 630 A at 40 °C down to 520 A at 70 °C, so if your panel ambient runs hot, size the load accordingly. This breaker ships with an undervoltage release (UVR) and a full auxiliary switch complement: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type). That means you get both remote status and undervoltage protection out of the box — no separate add-on modules to source for basic signaling.
The breaker measures 110 mm deep, 138 mm wide, and 248 mm tall. It mounts into a standard MCCB footprint — no special adapter plate needed for most SENTRON panelboards. Verify the bus-bar spacing against your existing riser; the 138 mm width is typical for 3-pole frames at this ampacity.
