The communication function (likely via PROFIBUS or PROFINET on the 3VA2 platform) lets a PLC or BMS read trip events and load current — useful for predictive maintenance on a critical feeder.
The 3VA2063-7KQ36-0AA0 measures 181 mm high, 105 mm wide, and 86 mm deep — a standard 3-pole MCCB footprint that fits most Siemens and third-party panelboards.
With 63 A continuous rating and interrupting capacity that drops to 3 kA at 690 V, this breaker is sized for low-voltage distribution up to 800 V insulation class (Ui). The ETU860 release supports zone-selective interlocking (ZSI) when paired with downstream SENTRON breakers, which reduces arc-flash energy on a fault by limiting the upstream trip delay. No undervoltage release or shunt trip is built in, so add those externally if the application requires emergency-off or undervoltage protection.
