For a 480 V delta or 400 V wye distribution panel, the 187 kA figure covers most high-fault installations. At 690 V the 40 kA rating still handles industrial motor-drive bus faults within typical transformer sizes. Above that, derate per the curve: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. In a sealed enclosure without forced airflow, the internal ambient can easily reach 50–55 °C, so the effective current capacity drops to 575–593 A. The dimensions — 248 mm height, 138 mm width, 110 mm depth — fit standard MCCB panel cutouts; the 110 mm depth leaves clearance behind the gland plate for the shunt trip wiring. ## Integrated accessories This variant includes a factory-integrated shunt trip (STL) release, order code 3VA9688-0BL33, for remote tripping via a control signal. The undervoltage release is not fitted, and there is no ground-fault monitoring module. The trip indicator is absent, so fault-event logging relies on the auxiliary switch state or the ETU320's internal event counter accessible via the communication module slot.","metaTitle":"Siemens SENTRON 3VA2463-6HL32-0KC0 MCCB, 630 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2463-6HL32-0KC0 molded case circuit breaker, 630 A rated at 40 °C, 3-pole, ETU320 electronic trip, 242 kA at 240 V.
