The 75.6 kA at 415 V and 52.5 kA at 500 V give this MCCB headroom for most industrial transformer-fed panels. ## Ground-fault and monitoring This variant includes summation-current ground-fault monitoring — it measures the vector sum of the L-conductors to detect leakage to earth. That is a practical feature for panels feeding motor circuits or long cable runs where nuisance tripping from capacitive leakage is a concern. No undervoltage release or communication function is fitted on this order code, so it is a straight thermal-magnetic protector with ground-fault sensing. ## Panel integration The 3-pole footprint matches the existing cutout for most 160 A MCCBs; verify the busbar pitch if retrofitting into an older panel. Maximum power loss is 25.5 W, so ventilation in a sealed enclosure should account for that heat at full load.","metaTitle":"Siemens SENTRON 3VA2116-4HM32-0AA0 MCCB, 160 A, 75.6 kA at 4","metaDescription":"Siemens SENTRON 3VA2116-4HM32-0AA0 molded case circuit breaker, 160 A continuous, 75.6 kA breaking at 415 V, 3-pole, line protection.
