Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 187 kA at 240 V tells you this breaker is sized for high-fault installations — think transformer secondaries or large motor control centers where the available fault current is well above what a standard 65 kA or 100 kA MCCB can handle. The 3.7 kA at 690 V is a reminder that at higher voltages the arc extinction limits the interrupting rating; if your system runs 690 V, verify the fault current stays under that threshold. The magnetic trip range spans 95 A to 756 A, adjustable via the internal trip unit. That wide band lets you set the instantaneous pickup to coordinate with downstream breakers or motor starters — set it low enough to protect the feeder, high enough to ride through inrush without nuisance trips. Dimensions: 181 mm height, 105 mm width, 86 mm depth. The 105 mm width is the standard 3-pole MCCB footprint for this frame size — it occupies three 35 mm DIN-rail modules (roughly 105 mm total). The breaker includes a shunt trip (STL) release and a full complement of auxiliary switches: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ configuration). That gives you remote status and trip indication without adding external relay logic. ## Environmental and operational limits","metaTitle":"Siemens 3VA2163-5JQ32-0KL0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA2163-5JQ32-0KL0 SENTRON molded case circuit breaker, 63 A rated, 3-pole, 187 kA breaking capacity at 240 V.
