Its breaking capacity of 75.6 kA at 415 V AC (and 121 kA at 240 V) means it can safely interrupt high-fault currents without upstream cascading — critical for maintaining selectivity in a multi-level distribution.
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.
