Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, and still holds 75.6 kA at 500 V, dropping to 3.7 kA at 690 V. That 187 kA figure at 240 V means it can clear a bolted fault on a high-capacity transformer secondary without upstream fuses needing to coordinate — a real advantage for main-breaker applications in 240 V delta or 208Y/120 V panels where available fault current runs high. A communication function is built in, supporting integration with energy management or remote monitoring systems. The trip indicator confirms the breaker has opened on fault, and the adjustable thermal-magnetic trip unit has an initial setting of 16 A and a full-scale value of 63 A, giving the specifying engineer a wide range to match the downstream load without swapping the breaker frame. ## Panel fit and physical integration The 3VA2163-5JQ32-0BH0 measures 105 mm wide by 181 mm tall by 86 mm deep — a compact footprint for a 63 A frame with this interrupting capacity. With a maximum current rating of 756 A and a minimum of 95 A for the trip unit adjustment range, this breaker can be set to protect a feeder as small as 95 A while the frame itself can pass through 756 A without damage — useful for a tap conductor where the upstream breaker is larger. At 690 V the breaking capacity drops to 3.7 kA, so it is not suited for 690 V industrial mains with high fault current; that application calls for a higher-rated frame.","metaTitle":"Siemens 3VA2163-5JQ32-0BH0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2163-5JQ32-0BH0 molded case circuit breaker, 63 A rated, 3-pole, 187 kA breaking at 240 V.

The 3VA2163-5JQ32-0BH0 carries a higher rated current (63 A vs the 16 A of the 3VA2116-5JP32-0AE0) and higher interrupting capacity, so it can replace the smaller breaker without panel modifications as long as the conductor sizing and upstream protection are rated for 63 A.
