Its 4-pole configuration handles three-phase plus neutral, and the interrupting capacity hits 440 kA at 240 V, 330 kA at 415 V, and 52.5 kA at 690 V, so it can be placed upstream of high-fault transformers or large motor control centers without cascading coordination concerns. This is a line-protection design with an integrated ground-fault monitoring version that uses summation current formation on L+N conductor — useful for detecting leakage on solidly-grounded systems without a separate GFCI module.
The 86 mm depth means it will clear most standard-depth enclosures, but check gland-plate clearance if the breaker sits near the back wall.
Thermal and electrical limits
Maximum power loss is 7.7 W — negligible for enclosure heat budgeting but worth noting for high-density panels. The initial trip setting is 20 A with a full-scale value of 100 A, suggesting an adjustable thermal-magnetic or electronic trip unit. No undervoltage release is fitted, and there is no trip indicator.
