The 100 A rating holds flat from 40 °C to 50 °C, then derates to 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C — so if the panel ambient runs above 50 °C, the breaker's effective capacity drops; size the load accordingly. Its interrupting ratings are substantial: 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 ETU850 electronic trip gives adjustable curves and communication capability — this variant includes a communication function and an undervoltage release (UVR). No ground-fault monitoring or phase-failure detection on this unit.

Frequently asked questions
Will 3VA2110-5KP32-0CL0 drop into a panel that was specified around 3VA1112-5EF32-0CA0 without rewiring?
The 3VA2110-5KP32-0CL0 is a 3-pole 100 A MCCB with an ETU850 electronic trip, while the 3VA1112-5EF32-0CA0 is a different frame and rating. Panel fit depends on bus-bar spacing and cutout dimensions — verify the frame size matches your existing panel layout before swapping.
