The Siemens 3VA1163-5ED32-0AG0 is a SENTRON 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current at 40 °C, with a TM210 thermal-magnetic overcurrent release. Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — figures that govern selectivity coordination in high-fault panels. The TM210 release is fixed (non-adjustable thermal and magnetic trip), suited for line protection of feeders and distribution boards where coordination studies are already locked.
At 55 °C it carries 60.48 A, at 60 °C it carries 59.22 A, at 65 °C it carries 57.96 A, and at 70 °C it carries 56.7 A — a gentle slope that keeps the 60 A bus rating viable in a warm enclosure. The 70 mm depth and 76.2 mm width fit standard 3-pole MCCB mounting footprints; the 130 mm height clears most distribution panel covers with room for gland plates. The trip indicator (mechanical flag) is visible through the front cover, so a walk-by inspection confirms the breaker state without opening the door.
