The 121 kA at 415 V and 79 kA at 500 V confirm it holds up under European 400 V line-to-line service. At 690 V the rating drops to 3.4 kA, so this is not the breaker for a 690 V motor center; keep it on 240–500 V distribution. The electronic trip unit is an ETU350, a line-protection (non-selectivity-optimized) curve that trips on overload and short-circuit without the intentional delay of a selective release. That makes it a straightforward fit for feeder or branch positions where you want fast clearing, not staged coordination. ## Thermal derating and endurance — what the 63 A rating actually means at panel ambient At 55 °C it derates to 60.6 A, at 60 °C to 58.3 A, and at 70 °C to 53.6 A. The mechanical endurance is 20,000 cycles, which is typical for a distribution MCCB; not a motor-switching duty cycle, but fine for infrequent manual or remote operation. ## Auxiliary contacts and shunt trip — what the 3VA2063-5HN36-0JH0 carries onboard Factory-fitted with two auxiliary switches plus one trip-alarm switch (the HQ configuration). That gives you two form-C contacts for status feedback (open/closed) and a dedicated alarm contact that changes state only on a trip event — useful for remote annunciation or a PLC input that distinguishes a manual open from a fault. The shunt trip (STL) is included for remote tripping via a control voltage; the integrated auxiliary trip module is order code 3VA9688-0BL32 if you need a replacement. The basic switch assembly (the removable switching mechanism) is 3VA2063-5HN36-0AA0. That is a standard 3-pole MCCB envelope for this current class; it will drop into most SENTRON 3VA panelboard or enclosure cutouts without modification.","metaTitle":"Siemens 3VA2063-5HN36-0JH0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-5HN36-0JH0 molded case circuit breaker, 3-pole, 63 A, 187 kA at 240 V.

The selectivity curve on the 3VA2163 adds intentional delay for coordination; the 3VA2063 clears faster.
