Its breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the voltage-dependent curve means the interrupting rating drops sharply above 500 V, so verify the available fault current at your system voltage before specifying.
At 86 mm deep, 105 mm wide, and 181 mm tall, this MCCB fits standard Siemens SENTRON mounting footprints; the 105 mm width is the same across the 160 A frame size, so a panel laid out for a sibling in this family accepts the 3VA2116-5HM36-0AA0 without re-drilling the gland plate.
Ground-Fault Monitoring and Protection Features
The breaker includes summation-current ground-fault monitoring on the L-conductor — it measures vector sum of phase currents to detect leakage to earth, which is useful for equipment protection in solidly-grounded systems. It does not include an undervoltage release, a voltage-trip trigger, or a communication function — this is a straight line-protection device with no auxiliary electronics.
