What this MCCB does and where it fits
Its 187 kA breaking capacity at 240 V (121 kA at 415 V, 75.6 kA at 500 V, 3 kA at 690 V) means it can safely interrupt high-fault currents without upstream coordination issues — critical for installations with high available fault current. The part includes summation-current ground-fault monitoring on the L-conductor, so it can detect leakage without a separate GFCI module.
The adjustable thermal-magnetic trip range (minimum 38 A, maximum 300 A) allows coordination with downstream feeders. Dimensions: 181 mm height, 105 mm width, 86 mm depth — fits standard 3-pole MCCB panel cutouts.
Integration notes
No undervoltage release or communication function on this variant — it is a plain line-protection breaker with ground-fault monitoring.
