The Siemens SENTRON 3VA2163-6HN36-0AD0 is a 3-pole molded case circuit breaker rated for 63 A continuous current. It is designed for line protection in distribution panels, with no communication function, undervoltage release, or ground-fault monitoring — a straight thermal-magnetic or electronic trip unit for primary feeder protection. The interrupting capacity is 242 kA at 240 V AC, which drops to 187 kA at 415 V and 440 V, and 121 kA at 500 V — meaning it can safely clear high-fault currents in low-voltage switchgear without upstream coordination. At 690 V the rating falls to 3.7 kA, so this is not a 690 V main breaker unless fault current is tightly limited.
Rated current and thermal performance
The breaker holds its full 63 A rating across the entire 40 °C to 70 °C ambient range with no derating — the spec table lists 63 A at every 5 °C step from 40 °C through 70 °C. That simplifies panel design in warm enclosures or adjacent to heat-producing gear. Maximum power loss is 4 W per pole at rated current.
Physical fit and panel integration
Dimensions are 105 mm wide, 181 mm high, 86 mm deep. The 105 mm width is standard for a 3-pole frame in the SENTRON 3VA2 series, so it fits existing panel cutouts and bus-bar spacing designed for that form factor. The breaker ships with 3 auxiliary switches (HQ design) integrated; no auxiliary release or voltage trip module is included. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C.
