What this 3VA2110-5JQ32-0CC0 does on the line
Its rated continuous current Iu is 100 A, and it carries a full-rated current up to 50 °C — at 55 °C it derates to 96.25 A, at 60 °C to 92.5 A, at 65 °C to 88.75 A, and at 70 °C to 85 A. The interrupting ratings are where this breaker earns its panel space: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V. The integrated undervoltage release (UVR) and the two HQ auxiliary switches provide control interface for safety circuits and status feedback. It includes a communication function — for PROFIBUS or PROFINET via the 3VA communication modules — so it fits into a digital switchgear scheme where you want trip data and remote operation.
Panel fit and physical constraints
The trip indicator is not present on this variant, so fault status relies on the auxiliary switches or the communication interface.
