The Siemens SENTRON 3VA2163-5KP32-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 63 A across the full ambient range from 40 °C to 70 °C — no derating needed in a warm panel. Its interrupting capacity hits 121 kA at 415 V and 187 kA at 240 V, so it handles high-fault utility feeds without cascading upstream — a key spec for main breaker or high-SCCR panel positions.
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA2 frame that fits existing DIN-rail or panel-mount cutouts without rework. Rated insulation voltage of 800 V gives headroom for 690 V systems; the breaker carries a 6.5 W maximum power loss, manageable in a ventilated enclosure.
Interrupting ratings: 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 — the 690 V figure is low, so verify coordination if that voltage is in play.
