Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and still delivers 75.6 kA at 500 V, so it handles high-fault scenarios downstream of large transformers without cascading upstream. The communication function means this breaker can integrate into a networked power monitoring scheme, though the specific protocol isn't listed in the basic spec; expect PROFIBUS or PROFINET capability typical of the SENTRON 3VA2 platform. That simplifies panel design in non-climate-controlled environments. The 187 kA at 240 V is the headline interrupting capacity; at 690 V it drops to 3.7 kA, so verify the available fault current at your service voltage. The 6.5 W maximum power loss means minimal heat contribution inside a crowded enclosure — relevant when stacking multiple breakers on a DIN rail assembly. The undervoltage release (UVR) is factory-integrated, not a field-addon kit. That saves installation labor but locks the BOM to this specific order code if UVR is required. The trip indicator provides local mechanical flag for troubleshooting — no need to power a display to see if the breaker tripped on fault. Dimensions of 105 mm wide × 181 mm tall × 86 mm deep (4.13 × 7.13 × 3.39 inches) place it in the standard SENTRON 3VA2 footprint. It mounts via screw-on lugs or busbar connection, not snap-on DIN rail — typical for MCCBs at this frame size. The 3-pole design with neutral switching handled externally (no integrated neutral pole in this variant) means the panel layout should allocate space for a separate neutral bar or 4-pole breaker if full isolation is required.","metaTitle":"Siemens 3VA2163-5JQ32-0CH0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2163-5JQ32-0CH0 molded case circuit breaker. 63 A rated, 3-pole, 187 kA at 240 V.
