The Siemens SENTRON 3VA2163-6HL32-0DL0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It is designed for line protection in distribution panels, with a breaking capacity that starts at 242 kA at 240 V and holds at 187 kA through 440 V, then steps down to 121 kA at 500 V and 3.7 kA at 690 V. The 63 A rating is the frame size; the actual trip unit is set at that value, so it protects a 63 A bus or feeder without needing an external adjustment.
Panel fit and auxiliary configuration
The basic switch core is order code 3VA21636HL320AA0, so the auxiliary and release modules are factory-integrated, not field-added.
No ground-fault monitoring version is fitted (specified as Without), and no communication function is built in. The breaker is a line-protection design, meaning its trip curve is optimized for cable and busbar protection rather than motor or generator protection.
