That's a steep derate above 500 V — the 690 V figure tells you this frame is sized for low-voltage distribution, not 690 V motor circuits. Power loss hits 162 W at full load, so the enclosure needs ventilation or derating if you pack several of these in a sealed panel. ## Thermal derating and trip unit Current rating drops steadily from 630 A at 40 °C to 520 A at 70 °C — a loss of 110 A across 30 K. If your panel ambient runs 55 °C, the usable rating is 575 A, not the nameplate 630 A. Plan the load accordingly. It's a straight thermal-magnetic replacement with electronic adjustment — set the long-time and short-time pickup via the front dials, and you're done. No Modbus, no PROFIBUS, no remote reset. That gives you three dry contacts for status feedback — one for the breaker position, one for the alarm on fault trip. Enough for a PLC input card, not enough for complex interlocking. ## Mechanical fit and environment The -25 °C floor means it's fine for unheated electrical rooms in northern climates, but not for outdoor enclosures in a deep freeze.","metaTitle":"Siemens 3VA2463-5HL32-0AJ0 SENTRON MCCB, 630 A, 3-Pole, ETU3","metaDescription":"Siemens 3VA2463-5HL32-0AJ0 SENTRON molded case circuit breaker, 630 A rated at 40 °C, 3-pole, line protection, ETU320 trip unit.
