Interrupting capacity and thermal performance
The 3VA2110-8HL32-0AA0: This MCCB delivers 440 kA interrupting capacity at 240 V AC, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 53 kA at 690 V — figures that place it in the high-fault tier for industrial switchboards where upstream transformer or generator fault currents are substantial. That simplifies panel design for a 100 A feeder in a non-climate-controlled plant. Maximum power loss is 7.7 W, which keeps heat dissipation low enough that you can group breakers in a standard IP40 front panel without forced ventilation.
At 105 mm wide, 181 mm tall, and 86 mm deep, the 3VA2110-8HL32-0AA0 fits the standard SENTRON 3VA2 footprint.
