At 240 V the interrupting rating is 440 kA; at 415 V it is 330 kA, and at 500 V it is 220 kA. Those numbers are the short-circuit current rating (SCCR) the breaker can clear without self-destruction, and they govern the available fault current the upstream transformer can deliver to this panel position. ## Trip unit and selectivity notes The ETU320 is an electronic trip unit with a current adjustment range from 95 A minimum to 756 A maximum — those are the pickup settings for the long-time element, not the continuous rating of the breaker itself. The continuous current is fixed at 63 A by the frame and the thermal path; the trip unit settings govern the protection curve above that. For selectivity studies, the ETU320 gives you an I²t on/off for short-time delay, which lets you coordinate with downstream MCCBs or fuses.","metaTitle":"Siemens 3VA2063-8HL46-0AA0 MCCB, 63 A, 4-Pole, ETU320, 440 k","metaDescription":"Siemens SENTRON 3VA2063-8HL46-0AA0 molded case circuit breaker, 63 A continuous, 4-pole, ETU320 release, 440 kA at 240 V.
