Interrupting capacity across voltage levels
The 3VA2063-5JQ32-0AC0 delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That 121 kA at 415 V is the figure that matters for most European industrial distribution — it tells you the breaker can clear a bolted fault on a 400 V bus without welding its contacts or venting arc gas into the enclosure.
Physical fit and panel integration
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA2 frame footprint that drops into existing DIN-rail or screw-mounted panel layouts without re-drilling. The 86 mm depth keeps it clear of shallow enclosure doors.
Built-in communication and auxiliary switching
This variant includes a communication function for remote monitoring or integration with a building management system, plus two auxiliary switches (HQ design) for status feedback to a PLC or indicator panel. The supplied basic switch carries order code 3VA20635JQ320AA0 — useful for cross-referencing replacement internal assemblies.
Thermal performance and power loss
The 63 A rating holds flat from 40 °C through 70 °C ambient — no derating curve to calculate for warm panel environments. Maximum power loss is 5.4 W, which keeps heat buildup manageable in a densely packed enclosure.
