Breaking capacity runs 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V — so the interrupting rating drops sharply above 500 V; verify the available fault current at your system voltage before committing the BOM line. Maximum power loss is 162 W — account for that heat in the enclosure ventilation calculation. ## Temperature derating and enclosure planning Rated continuous current drops from 630 A at 40 °C to 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. ## Trip unit, auxiliaries, and release options The ETU850 overcurrent release provides electronic protection with adjustable pickup and time-delay settings for long-time, short-time, instantaneous, and ground-fault (though this variant ships without ground-fault monitoring). A shunt trip (STL) design of the auxiliary release is fitted — order code 3VA9688-0BL32 for the integrated auxiliary trip, and 3VA2463-5KP32-0AA0 for the supplied basic switch. A voltage trigger is present, and a communication function is included for integration into a higher-level monitoring system. No undervoltage release or phase failure detection on this variant.","metaTitle":"Siemens 3VA2463-5KP32-0JH0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0JH0 molded case circuit breaker, 630 A rated, 187 kA breaking at 240 V, ETU850 trip unit, current production.
