It's a line-protection device, meaning it's the main feeder breaker or a large subfeed breaker in a distribution panel, not a motor-protection or generator breaker. The interrupting ratings are where this part earns its keep: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.8 kA at 690 V. Those numbers mean it can safely clear a bolted fault at the main switchboard without the arc flash escalating — the 330 kA at 240 V is the headline figure for high-fault industrial services in North America, while the 242 kA at 415 V covers European 400 V panels. The N-conductor protection is adjustable: OFF or 100% of the phase rating. The adjustable response time (tr) ranges from 0.5 to 17 seconds, which lets you coordinate with downstream breakers for selectivity. IP40 on the front. 4-pole width of 140 mm. Power loss is 4 W maximum. If you need remote monitoring or trip indication, you'll add auxiliary switches or shunt trips externally.","metaTitle":"Siemens 3VA2163-7HL42-0AA0 SENTRON MCCB, 63 A, 4-Pole, 330 k","metaDescription":"Siemens SENTRON 3VA2163-7HL42-0AA0 molded case circuit breaker, 63 A rated continuous current, 4 poles, ETU320 release.
