Three poles, line-protection design, no undervoltage release or communication function onboard. This is the version you spec when you need a straight thermal-magnetic or electronic-trip MCCB for a distribution panel, motor control center, or feeder circuit, and you want the high interrupting capacity that the 3VA2 frame carries.
Breaking capacity — what the voltage-dependent numbers mean for coordination
This breaker delivers 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. The sharp drop to 3.7 kA at 690 V means this is not a 690 V main breaker; it is a 240–500 V device with a 690 V rating that covers incidental or lightly-faulted circuits only.
Ground-fault monitoring version
This variant is configured for summation-current ground-fault monitoring on the L-conductor — meaning it uses a summation CT around the phase conductors to detect residual current. That is the standard approach for solidly-grounded systems where you want ground-fault protection without a separate GF relay. The 3VA2116-6HM32-0AA0 does not include a trip indicator or voltage trigger, so ground-fault events will not leave a visible flag on the breaker face; plan for an external indication if the application requires it.
