The Siemens 3VA2163-5HL32-0AH0 is a SENTRON molded case circuit breaker rated 63 A continuous current across the full ambient range from 40 °C to 70 °C, meaning no derating is needed for typical panel temperatures up to 70 °C. The 3-pole unit delivers 187 kA interrupting capacity at 240 V and 121 kA at 415 V, which covers most industrial service-entrance and distribution applications where fault currents run high.
Interrupting ratings across voltage levels
Interrupting capacity drops from 187 kA at 240 V to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and finally to 3.7 kA at 690 V. The steep decline above 500 V means this breaker is sized for 240–480 V systems where high fault current is expected; at 690 V it handles only modest fault levels.
Built-in auxiliary switch configuration
The basic switch assembly carries order code 3VA21635HL320AA0. No separate voltage trigger or communication function is present — status signalling is limited to the auxiliary contacts and the trip indicator.
Mounting dimensions for panel integration
The 86 mm depth (3.39 in) fits standard MCCB mounting footprints in distribution panels. Width of 105 mm (4.13 in) is consistent with 3-pole SENTRON 3VA2 breakers; check the backplate cutout and busbar spacing against the existing panel layout.
