That 630 A figure is the continuous current at 40 °C ambient; above that, the breaker derates in a known curve — 600 A at 45 °C, 570 A at 50 °C, down to 450 A at 70 °C — so the real ampacity in a warm enclosure is lower than the nameplate. Breaking capacity is the other headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. The high 187 kA at 240 V makes this unit suitable for high-fault-capacity industrial services where standard breakers would need series ratings. ## Line protection, auxiliary contacts, and undervoltage release This is the line protection version (not generator or motor protection), meaning the trip curve and accessories are configured for feeder and main breaker duty. Dimensions are 184 mm wide by 248 mm tall by 110 mm deep — a 4-pole frame that occupies a defined footprint in the switchboard.","metaTitle":"Siemens 3VA2463-5JP42-0DD0 SENTRON MCCB, 630 A, 4-Pole, ETU5","metaDescription":"Siemens SENTRON 3VA2463-5JP42-0DD0 molded case circuit breaker, 630 A at 40 °C, 4-pole, ETU550 trip unit, 187 kA at 240 V.
