Its 86 mm depth, 140 mm width, and 181 mm height fit standard MCCB mounting footprints — no special adapter plate needed for most 160 A frame cutouts. Breaking capacity is the headline selector here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V.
Thermal performance and ground-fault monitoring
Power loss is 4 W maximum, low enough to ignore in thermal busbar calculations for most panel layouts. Ground-fault monitoring uses summation current formation on the L + N conductors, meaning it measures vector sum of phase and neutral currents to detect leakage. This is a residual-current detection method built into the breaker, not an add-on module — simplifies wiring in TN and TT systems where neutral must pass through the sensor.
