At 45 °C it carries 612 A, at 50 °C it carries 593 A, at 55 °C it carries 575 A, at 60 °C it carries 557 A, at 65 °C it carries 538 A, and at 70 °C it carries 520 A. The maximum power loss is 162 W, so factor that into the enclosure's thermal budget. The 3VA2463-5HN42-0KH0 measures 248 mm high, 184 mm wide, and 110 mm deep. That 184 mm width is the 4-pole footprint — it won't drop into a 3-pole cutout without a wider backplate. For a line protection breaker in a main feeder position, the shunt trip gives you a remote open signal — useful for emergency-stop circuits or PLC-based load shedding.","metaTitle":"Siemens 3VA2463-5HN42-0KH0 SENTRON MCCB, 630 A, 4-Pole, 187","metaDescription":"Siemens 3VA2463-5HN42-0KH0 SENTRON molded case circuit breaker, 630 A continuous at 40 °C, 4-pole, 187 kA breaking at 240 V.
