The Siemens SENTRON 3VA1163-6EE42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, with a TM220 thermal-magnetic overcurrent release and a continuous current of 63 A at 40 °C. Its interrupting capacity reaches 220 kA at 240 V AC, dropping to 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V — figures that define its suitability for high-fault utility or transformer-fed distribution panels.
The breaker holds 63 A continuously up to 50 °C ambient; above that it derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C — so in a warm enclosure you lose about 5 A by the time you hit 70 °C. Dimensions are 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole MCCB that fits a standard DIN-rail or panel-mount footprint; the front face carries IP40 protection, so it is splash-safe in a dry enclosure but not washdown-rated. Maximum power loss is 17.3 W, which matters for thermal management inside a sealed cabinet — factor that into your enclosure cooling budget.
The SENTRON 3VA series carries IEC/EN 60947-2 certification for molded case circuit breakers; the manufacturer provides RoHS and REACH declarations as standard compliance documentation.
