SENTRON 3VA2163-5HN36-0JA0 — 63 A MCCB with shunt trip, line protection duty
The Siemens 3VA2163-5HN36-0JA0 is a 3-pole SENTRON molded case circuit breaker rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity runs 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. Dimensions are 105 mm wide by 181 mm tall by 86 mm deep — standard SENTRON 3VA frame size for 63 A.
The 187 kA at 240 V is the headline number, but the 121 kA at 415 V is the more common coordination figure for 400 V class distribution. At 690 V the breaking capacity drops to 3.7 kA — that's still adequate for most 690 V systems where fault current is typically lower, but verify against your transformer impedance and cable run. The 63 A rating holds steady through 70 °C ambient, so no temperature derating curve to apply in a warm panel.
Mounts on a standard SENTRON 3VA mounting plate in a switchboard or enclosure. The 105 mm width fits alongside other 3VA breakers for multi-pole or multi-feeder layouts. Shunt trip wiring requires a control voltage source — verify polarity and voltage rating per the release specification before energizing. No communication module or auxiliary contacts are included on this base variant; add them separately if remote status indication is needed.
