63 A MCCB with high interrupting capacity
The Siemens SENTRON 3VA2163-6HN36-0CA0 is a 3-pole molded case circuit breaker (MCCB) rated for continuous current of 63 A across ambient temperatures up to 50 °C, with a slight derating curve above that — 60.6 A at 55 °C, down to 53.6 A at 70 °C. Its headline breaking capacity hits 242 kA at 240 V AC, falling to 187 kA at 415/440 V, 121 kA at 500 V, and 5 kA at 690 V.
ETU350 release and undervoltage protection
The UVR design uses a separate auxiliary trip coil (order code 3VA9608-0BB24) that can be replaced independently.
Dimensions are 181 mm height, 105 mm width, and 86 mm depth — a compact footprint for a 63 A MCCB with 242 kA interrupting capacity.
