The Siemens SENTRON 3VA2163-8HL32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current, built around the ETU320 electronic trip unit. Rated insulation voltage is 800 V, and the interrupting capacity hits 440 kA at 240 V AC, 330 kA at 415 V, and 220 kA at 500 V — numbers that tell you this breaker is sized for high-fault locations like a main service entrance or a large distribution panel where the available fault current is serious. The 63 A rating holds steady across the full operating temperature range from -25 °C to 70 °C, so no derating headache in a warm enclosure.
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into a SENTRON panelboard or a DIN-rail-mounting base without surprises.
