The 3VA2110-6HL32-0CA0: The interrupting rating is what sets this MCCB apart for high-fault installations: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. That 242 kA figure at 240 V gives you headroom for transformer-secondaries or large motor-control centers where fault current can spike. At 690 V the rating drops to 3.7 kA — still adequate for most 690 V industrial loads, but worth checking against your available fault current if you're feeding a 690 V bus.
Undervoltage release and panel fit
The UVR is factory-installed; no field retrofit required.
Thermal performance across temperature
That's unusual; many MCCBs start derating above 40 °C. Maximum power loss is 12.5 W, which is modest for a 100 A frame.
