Breaking capacity and what it means for your panel
The 3VA2116-6HN32-0CL0: This MCCB delivers 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 5 kA at 690 V.
Thermal derating — the real-world current
At 55 °C it derates to 154 A, at 60 °C to 148 A, at 65 °C to 142 A, and at 70 °C to 136 A. The ETU350 electronic trip handles the curve, but the thermal limit is in the frame and contacts.
Auxiliary and undervoltage release configuration
No communication module or phase-failure detection on this variant.
Physical fit and mounting
Latching endurance rated at 20,000 operations — mechanical, not electrical; the electrical endurance will be lower at full load.
