The 630 A figure is the base rating at 40 °C; above that ambient the breaker derates in steps — 612 A at 45 °C, 593 A at 50 °C, down to 520 A at 70 °C — so the real-world continuous current depends on your enclosure temperature, not just the nameplate number. 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. At 690 V the 9 kA figure is lower, which is typical for this frame size; if your system runs 690 V with high fault potential, verify coordination with the upstream device. The ETU350 release is an electronic trip unit — adjustable, more precise than thermal-magnetic for coordinating with downstream breakers in a selective scheme. Maximum power loss is 162 W, which matters for heat buildup in a sealed enclosure; factor that into your thermal calculation.","metaTitle":"Siemens 3VA2463-5HN32-0AA0 SENTRON MCCB, 630 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2463-5HN32-0AA0 molded case circuit breaker, 630 A continuous, 3-pole, ETU350 release.
