Its headline number is the interrupting capacity: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. Those figures tell you the maximum fault current this breaker can safely clear at each voltage level without welding contacts or rupturing the case — critical for selectivity studies and SCCR compliance on the line side of a motor starter. Rated continuous current Iu is 63 A, and it holds that rating flat from 40 °C through 50 °C ambient. Above 50 °C it derates: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, 56.7 A at 70 °C. If your panel ambient runs hot, the 63 A frame gives you headroom before you hit the thermal limit. The ETU350M electronic overcurrent release handles the protection curve — adjustable thermal and magnetic settings for motor starting inrush without nuisance trips. Phase failure detection is built in, so a lost phase on the line side trips the breaker before single-phasing cooks the motor. ## Lifecycle and sourcing reality The basic switch assembly carries order code 3VA2163-7MN32-0AA0, and the integrated auxiliary trip is 3VA9608-0BB25 — both are serviceable sub-assemblies if you're stocking spares for a panel fleet. ## Panel integration and physical fit Dimensions: 105 mm wide, 181 mm tall, 86 mm deep. That's a standard 3-pole MCCB footprint for a 63 A frame — mounts on a DIN rail or screws directly to a backplate. The 86 mm depth means it clears a 120 mm deep enclosure with room for wiring gutters. Two auxiliary switches HQ (high-qualified) are factory-fitted for status feedback to a PLC or annunciator. The undervoltage release (UVR) is built in — it drops the breaker when control voltage falls below the dropout threshold, which is standard for emergency-stop circuits that need to fail-safe on power loss. Maximum power loss is 75 W — that's the heat the breaker dissipates at full rated current. Factor that into your enclosure thermal calculation; a 63 A MCCB dumping 75 W into a sealed box needs ventilation or derating.","metaTitle":"Siemens 3VA2163-7MN32-0DC0 SENTRON MCCB, 63 A, 330 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-7MN32-0DC0 molded case circuit breaker, 3-pole, 63 A, 330 kA interrupting at 240 V.
