The Siemens SENTRON 3VA2063-7JQ32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated at 63 A continuous current (Iu) across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling.
The interrupting ratings are the headline spec for this class: 330 kA at 240 V, 242 kA at both 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. The steep drop to 3 kA at 690 V is characteristic of this frame size; for 690 V applications requiring higher interrupting capacity, a larger-frame SENTRON (e.g., the 3VA2 160 A frame) would be the correct selection.
The 86 mm depth includes the case body and the rotary handle; verify clearance to the gland plate or enclosure door, particularly if a motor operator (optional accessory per the listing) is fitted. Front-face protection is IP40, suitable for dry indoor panel environments.
Trip unit and communication
The ETU560 electronic trip unit supports communication (the listing confirms a communication function is present), allowing the breaker to report status, trip events, and load current over a fieldbus or via the SENTRON powerconfig software. This makes the 3VA2063-7JQ32-0AA0 suitable for a monitored distribution panel where the maintenance team needs remote visibility of breaker state without a physical walk-down. The trip unit is line-protection configured — no ground-fault or undervoltage release built in, though those are available as add-on modules.
